TMI

I've been thinking a lot about manners lately. Working where I do provides you with a really good look at peoples nastier sides, even the employee's. But regardless there are just somethings that are just plain too rude to ask about, or so I thought. A Co-worker asked me what my GPA is and I was slightly stunned. Talking about grades seems so wrong unless your really close to the person and even then I'd still hesitate to ask how someone did. It's not like this person has any classes with me (we go to different universities) so there's not really much reason for her to be asking me about my grades. Am I being overly sensitive? To me it's like asking someone how much they make, just bad taste.
