this literally happens every single time to me. in group settings, with a friend, or a girl. i don't know why i tend to get this reaction maybe my presence is not very heavy when i'm present, but when i leave is when they notice. time and time again. -f
If you want to be with someone and you love them, tell them. Love everything about them even their faults and imperfections. It's what makes them better and unique. It makes them stand out from everyone else. Let them know you love them they way they are.
