I'm going to meet the girl at the railway station. I don't know what to say.

Try to be natural, face it with a relaxed attitude and pay attention to other people's preferences. You don't have to pretend to be excellent. You can't pretend for long. Try to show your true self. If you find anything that makes the other person uncomfortable, you can change it. If you are on the spot, you can say: I'm sorry. . . If you have a bad feeling, you should also show goodwill appropriately, such as a little caring greeting. Just accumulate experience slowly. If it is not your favorite personality and behavior, you can get away in time.
