Definitely sounds like she has issues. Not your problem to fix her, just keep your head down & survive her.
sounds like your mom is still in high school !
O fa'chris'sakes---he joined EP today!
Pegassus is right. I'd say it's obvious your mom has something against people who don't immediately strike her as being part of the cool kids group or in-crowd, but only she knows for sure and only she can tel you the reasons why.
It does strike me as strange for an adult to act this way. It sounds like she has some leftover issues from when she was a teen.
I think she's jelous because the vast majority of geeks make more money then her, and probably end up being her boss.
Your mom sounds immature and stuck-up. Tell her to grow up and stop being so ridiculously judgemental.
Ask her, not us.
