Well at least you're honest! Some people are kid people and some aren't. It's okay to express how you feel. I have just about enough patience for my own 2. When it comes to other people's kids, I cringe.
Don't take me wrong, my kids aren't perfect by any means...I just don't do other people's kids very well for very long.
Yes, I work at a school and the 30 minutes I spend with the Kinder class during my lunch duty is enough to drive someone stark raving mad!!!!!
