10. Don't be rude to service people
The way you treat other people in front of your date will tell much about you. Be kind and show you have decency.
11. Having overly high expectations
Maybe your first date will lead you to a serious relationship, but this is not a must. If things go unplanned, don't be sad, keep your head up and start anew.
12. Don't interrupt your date
You've already learned this from your parents: Show respect by listening to your date and give an answer when she or he finished the sentence. Yet, as mentioned above, in cases where you want to show you're listening actively, it might make sense to interrupt your date by comprehension questions.
13. Get drunk
This can simply destroy everything, as you lose power over your words and your body. One glass of alcohol can help to be less nervous, but please use it sparingly.
14. Don't stand your date up
Unfortunately, standing up a date has been more prevalent today than ever. Standing up a date is just outright disrespect. If you can't make it to the date or realized you're suddenly not interested, send a text – it only takes less than a minute to send you can't make it!
15. Don't be overly touchy or make the other person uncomfortable with over the top sex jokes
Green jokes are fun. They can help decrease the nervousness of the first date. However, you have to make sure to discuss boundaries and gauge your comfort levels both ways before getting into it. Being overly touchy or cracking sex jokes after sex jokes might not land well with your date.
