Well, I'll preface this by saying my girlfriend's kind of a wild and carefree type. If her doing weird little things drove me nuts, I'd probably be looking for another relationship. That said, I might find it a little disturbing... more for her than me. But I wouldn't be angry. If I thought it was inappropriate to the point that it bothered me, I'd just tell her and she probably wouldn't do it anymore. No reason to start a fight. Some people just have different boundaries.

It seems even more minor given AJ's gf's drug abuse which you mentioned awhile back. Now that would cause me to take notice.
