As a teacher, naming your child is close to impossible.

I could sit here and say that every single Mitchell I've ever taught has been a nightmare, and it's true and the name has very negative associations for me. That's not to say that there aren't lovely Mitchells out there - just that none of them ever ended up in my classroom.

Would I use the name myself? No.
Would I automatically assume a new Mitchell I come across is also a ratbag? No. I actually look forward to the day when someone may actually be able to redeem the name for me! As my nephew is doing a great job of doing with his (not Mitchell! But another name that has strong negative associations for me).
Yep, I got told this over and over when I named my son Mitchell (apparently no one had ever known a "nice" Mitchell, lol). But i did it anyway because I really liked the name You would love to have my boy in your class...he's an A grade student, a sporting champ, a role model for his classmates and has awesome manners. Not that I'm bragging or anything, LOL. At home, hmmm, slightly different story...he definitely has that "cheeky" Mitchell side, hehehe.
