So I have a small problem,
I am 20 from the Boston, Massachusetts in the U.S.
Considering that, I have absolutely no idea on what fun things I can do with a girl after I meet her. Sadly, I can't go to bars yet (drinking age in the U.S. is 21 and it is strictly enforced... The U.K. and all other countries have all the fun

).
I do not want to necessarily invite a girl out to lunch/dinner. For the most part I would like to see a girl, but I do not want to do anything that she could possibly consider a date, hence possibly getting nervous.
I usually have a party or other event on weekends, however girls can get easily distracted or busy on weekends. There is less of a chance that a lady will "flake" if I see her during the week.
However, another constraint is that many girls are busy with classes and studying during the week.
So I ask all of you guys what do you think some good weekday (also feel free to post weekend) ideas that a 20 year old could do with a girl he just met on the previous weekend?
