Ah highschool dating. When you can actually manage a date less than $40 lol. Besides dinner and movies, you can't really do much considering your budget. Assuming its cold where you are too, not much can be done outside. It'll just be uncomfortable. Then again, I have no clue where you reside and it could be warm. In which case, take her for a stroll through the park and talk about the many wonders of life lol, or just eachother.
