I would have asked her what his puny ass what threatening? I would tell her he knows where you live and to come by anytime. Though he wouldn't be man enough to do so. Bottom line until the divorce he needs to not be around the kids period!!! Obviusly he was if your girl recognised the shoes as his.

P.S. don't mention soiling his shaving products....just enjoy it everyday you shave in the morning!!;)
