I don't get it.....?

So according to my little sis I'm "the meanest big bwother in the whole wide worlds!" for scolding her, after she tickled me for like 2 hours NONSTOP. Not to mention I even told her not to tickle me cuz I'm PAINFULLY ticklish!!...And she thinks I'm mean?? I seriously wasn't trying to be but I just can't take being touched/tickled in certain areas...it makes me very uncomfortable.
