Years back I dated a guy whose family we sorta knew of, as their grandparents knew my grandparents back in Hungary, etc, etc. It wasn't shayach, but I gave it a few tries and now he's happily married.
Just today this boy's mother called to ask if I was "busy" as she had someone in mind=her nephew.
Talk about awkwardness!
If her nephew is anything like her son, my answer is "NO". But there's no way to politely ask that, as well as a few other questions to determine this.
And no, I ain't drunk-this truly happened this morning. (Doubt she was drunk either)
