What if she did know? Would that make her unselfish?I'd ask her where the thing used to crap. Bet she wouldn't know.
The neighbours would.
Strangely, the only person I have ever argued with on this subject, that have ever held their hands up and admitted their selfishness....is you (if its really you). I respected your honesty. Does it make you any less selfish????? ....NO.
