How in the world did Michael think that letter was from Debbie?
I mean seriously she has never given off any vibes that she liked him and it seems as if the only times she hung out with him was when Toni was with them anyway. And at times it seems like she was downright rude to him, how did he come to the conclusion that out of the blue she liked him? I can understand not figuring out it was Toni, since lots of girls secretly love their best friends and they remain clueless as hell but Debbie? That was a long stretch especailly since it is said that she's into older guys/
Just got secretly engaged to the best guy ever!!
