"Share a short letter to your ex-boyfriend."
Hmm.. This would be brief. Hihi.
Your loss! Bwahaha! (evil laugh)
Hehe. This may sound mean.. but I'm actually trying to be funny here. So don't take this letter (insert image of hand, pointing above) seriously.
I know we had our good times together, and of course, the bad times. All of those are in the past now. Whatever we had, that's between the two of us. Though it didn't work out, I did give it my best shot. Good luck. Take care 'coz I care. NOT! #evillaugh
Hahaha!! Still the same thought, I guess.
