If she invites you to dinner with her friends, she obvoiusly wants to show you off, which is *slap on the forehead* duh, plainly obvious she wants to get to know you better. Just think about it for a second. She seeks YOU out everyday, she laughs at YOUR goofy joke, she wonders about the next time you two will meet everytime she asks for your schedule times. Just when you go to show affection, don't jump in head first, got it? ^_^
