I have one now... But my perception of him has turned around lately. I'm starting to warm up to him a bit.

I think my prejudice to him had mainly to do with him not being potty trained (at 3.5 - I'm sorry but there's something more gross about changing a diaper when the kid can talk to me in full sentences while I do it) and his uninvolved and aloof parents. But potty training aside, he's easy. And his parents are confident in me and thankful of what I do.
