i just wanna say, i feel the same way about tickling, although i haven't tried this technique of halting it yet.
why the negative opinion about tickling? because, growing up, i was 'freakishly small' (as val likes to put it) and people thought it gave them license to hold me down and tickle me at will.
and the same goes for picking me up off my feet, by the way. just don't do it, okay?
