Wrong Number

So today, my home got a phone call that was a wrong number. But the person who called didn't know who they were calling (returning a page) and my mum assumed that maybe I did page this guy. So what does she do...gives him both my email address and cell number. What was she thinking? I had to give her a "lecture" on when to give things out to strangers and when not to. Didn't she take her own advise "Don't talk to strangers"
