childish play is one thing, when you know someone doesn't like to be held and tickled to the point of screaming and being told to stop and you continue time and time again is a dominance thing. Pushing her over the couch back and then pushing down on her legs when she is falling is not child play. Yanking on her arm and sending her into the back of the couch while she is talking with her girlfriend is not childs play.
are you serious? Any time someone doesn't listen to when someone says no while doing something to cause harm to you is abuse to me. When does it have to be abuse to you, when a bone is broken or fractured? Then its considered abuse?
