Um, lets just say, for saying sake...
That this kid that you love with all your heart, was bad to you one too many times

so you sorta deleted him from your friends list to make him squirm

and then he invited you to be his friend again and you refused so that he would squirm some more and then he invited you again but you accidentally navigated off the page before approving the invite.. Then you couldnt find the invite so you invited him but it told you you couldnt...
Lets say that happened, how would you go about getting that invite back?
