I love my own kids, and I really like some kids that belong to a few of my friends. But I do not necessarily like ALL children because they are children.
Some kids get on my nerves, mostly because they are ill-behaved and have poor manners.
I like kids that are well behaved and polite.
I have certain families that I enjoy having over, even though they are large families because the kids are neat and they play well with mine.
