My roommate tickles me often...but she hates being tickled. Often she'll poke me with her foot and I'll grab it and tickle her...she'll say 'no!' and pull her foot away...but then a minute later continue to poke me with her foot. I told her once that she should stop putting her foot near me if she didn't want me to tickle them...but she'll still do it. Not sure if she wants me to tickle her or not!...she's had a bad experience with tickling, so if I try she just says she doesn't like it...but then she will go and do what I stated above..maybe she just wants attention?
