This might appear to be the scariest night of your life, when you have to get ready to go out on your first date, but the key here is to stay calm and act like you usually do. Don’t try to be anyone else, and don’t try to do anything special. Be yourself and stay that way, it always works. A lot of people try to act differently, and eventually it catches on if you continue to date that person. Do not be nervous, this isn’t going to be heavy on you, you will get more chances if anything.
To make you feel better it probably isn’t any different on the other side with your date, both of you most likely feel the exact same way. So don’t worry about trying anything crazy, do something relaxing and start up a decent conversation. Also don’t get into anything personal! That never works.
