Have I made a personal joke at your expense? I certainly haven't made an offensive comment about your mom.

I see two possibilities regarding your comment:

1) You were serious about my mom
2) You were making a joke about my mom

I can't imagine it was #1, correct me if I'm wrong and I'll remind you personal attacks are not allowed by the rules of the forum.

Assuming it was #2, my point is that mom jokes are traded amongst friends. You and I are not friends. Therefore, don't joke about my mom.

My mom will be playing the part of Padme in this new Star Wars movie.
