For most daters, one of the main reasons of the first date is to get to the second, third, and fourth date, etc etc. I'm sure you know how the script ends. Sometimes it's harder to think about all the things you want to say or do on your first date, however, if you want to ensure that you never have a second date, do these things.
Show up late for your first date … and do not call to inform your date
It's inevitable that at one time or another you're going to be running late for a date. This is more appropriate if you live in a larger metropolitan city like New York or LA where traffic is notoriously bad. Running late for a date is a possibility that most people understand. However, you'll find very few people understanding of your being late to a date and not calling to inform them that you're going to be late. Usually nothing starts a date off worse, or ends a date quicker than arriving late without calling. 10-15 minute is the acceptable 'fashionably late' time period. Anything over that warrants a call.
Arriving with no plans for the evening
"I thought we would be spontaneous tonight." Let's not and say we did! That's what your date will be thinking the whole time while they're steaming about how ill prepared you are for the evening. It's not unreasonable for your date to have the expectation that you planned the evening. After all you're the one who asked them out on a date. It's usually a good idea to make sure you have a properly planned evening for the date and not leave things to chance at the last minute. At the last minute you'll often find that restaurant had no available reservations, the movie times did not match, and the ticket to the event has already been sold out.
Trying to advance to 'coupledom' to quickly
It's just a first date, not a binding agreement to a lifelong of activities and matching clothes. There's no sense in talking about all the things you can do together as a couple because you've yet to spend enough time together to decide if you want another date, let alone if coupledom is right for you. Just like you have to learn to crawl before you walk, and walk before you run, you have to learn to go on a successful amount of dates before you can begin to talk about being a couple … or sharing food. It's still me and you … not we and us.
Talking or comparing your date to your ex's
Nothing will get the ire of your date more than if you compare them to your previous relationships. Behind that polite laugh and fake smile is a cold veneer just hiring you'll compare them to your ex again so they have permission to rip out your tongue with your fork. Angerside, lamenting about your ex is in poor taste and poor judgment. There is a reason why you call them your ex and in its best to keep that part of your life in the past and enjoy the person in front of you. Even if they do not laugh at your jokes like your ex did!
Making your date the butt of every joke
Everyone likes a good laugh, but not necessarily at their own expense … all the time. If you're the type of person that enjoys telling a joke or two, remember the object of a joke is to have your date laughing with you and not about you. So it's always good to make fun of yourself first, before you attempt to make fun of your date.
Forgetting your date's name
There's certainly nothing wrong with informing your date that you had an enjoyable evening with them … and there's nothing wrong with thank Sue and Steve for a great date; as long as, Sue and Steve are your dates names. In your busy dating schedule it's possible to confuse the Wednesday date with the Friday one or vice versa. Certainly if you've had too much to drink, alcohol could have played a part. For whatever the reason, forgetting your dates name is a great way to leave an impression. A 'definitely not ever again' impression. Word association has been known to help the name remembering impaired.
No call no-show
Of all the dating faux pas you can do, this one is the grand daddy of them all. The ultimate classless thing that you can do to ensure that you will not get a second date is to pull a no call no-show before the date. Everyone should operate under a certain level of dating courtesy (or decency some would say) to inform your date if you're unable to make it for whatever reason. The only thing that should precede you from calling your date to inform them is that you will not be there an emergency, accident or death of you or a loved one. Nemo the goldfish which floating on the fish tank does not count. In the instance your death, your date will certainly have to forgive you for that.
