well... I was going to post something on this forum, but everytime I thought I had something to say I read a post which said it.. um... so FML! Gah.
I thought the quote was funny, but as someone pointed out, how could he not know she was ticklish? If she left him hand cuff her they should have been together long enough for him to know she was ticklish.. a little poke her, make her jump, yadda yadda.
Unless, he was looking online and accidentally stumbled apon a fetish site which saw people hand cuffed and tickled and never thought about tickling her.. and didn't think about just finding out if she's ticklish before she hand cuffed her since they had them hand cuffed on the site and then tickled.. i dunno, it's possible...
and like people said, you weren't there Babbles.. for all we know she could have forgiven him, maybe hit him a few times or whatever. She didn't say she broke up with her boyfriend... Since you're assuming things, I'm going to assume things that aren't there and say she forgave him and they're still together and everything is okay in their lives and he tickles her, just not with her being handcuffed...
FML is supposed to be funny.. even though I usually don't find them funny.. but that's what the site is for. And I'm sure she knew about the site before posting them, you don't just post something like that to a site without konwing about it.. and she's probably read the FML stories and found them funny, and so she thought her thing might be right for it. so yeah..
