SIL gave us a shirt, tie and trouser set for DS's birthday. He wore the shirt on the day, the rest was very very big. Her sons size in fact.
So, I log onto FB and happen to see her son wearing the exact same suit. Coincidence perhaps?
Except that I know, for sure, that she regifted my christmas presents last year from the state of the present and its packaging.
AIBU to think she let her son wear it first?
And if yes, I still have last years gift in fact, AIBU to give it back to her?
