Congrats on your scripts!
I'll give you my Mom-Advice that I give DDs about young men. Ignore everything they say and pay attention to everything they do (not original, but I like it!). Also, be FRIENDS. Hang out, have fun, no pressure. If romance blossoms from it, then wonderful. If it doesn't, you haven't lost anything, but have gained a friend. Yes, it may sting when he introduces you to his new GF one day, but if you are gracious about it, you'll be that much stronger and more well-balanced in your own relationships as they come along.
Have a wonderful time enjoying the fireworks! I'll be looking for you in August when we are back down...
