If it's not one thing, it's my mother

Ok, so she did it again!  She told on herself.  A while ago she told Tam and I that she came out to the livingroom today after getting dressed and asked "Daddy" to hook her bra in the back.  He asked if she wanted it hooked in the farthest hooks, she said yes.  When he had finished, he said "This doesn't look quite right, do you have this on right?"  Mom looked down and realized she had it on backwards and it was a front hooking bra....... What should we do?    Deb
