Sounds like you got friendzoned. Edit: just read the whole thing over. The bellybutton thing and the panty thing is kinda of a weird thing to send to a friend.
So yeah like lola said either that she thinks you're gay, or plans on doing something with you. But do not expect a relationship at all. She may want to get it on with you, but from that bff comment, that means she does not think of you as relationship material.
Play it like you've been doing if you want her. Just know you will probably never be her BF. (the age gap has something to do with that too).
Dude based on your other questions, you are obsessed with this girl. GET OVER HER!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
