Women do this all the time...marks their territory.
True story: Had a bad break up with one woman. After an appropriate mourning period when I knew there was no reconciliation possible, I gathered up her things, boxed them up and had them delivered to her with a civil CYA note. Included was a bra size 36C left at my apartment.
She was a 32B.
AHHHH...Revenge: A dish best served cold. (But crow should be eaten warm.)
