From the outside the life of a parent has many unappealing aspects. These people appear to have hardly any time to concentrate on reading a book, watching a movie, or engaging in an adult conversation with a friend.
But when I finally moved into the parent role myself the things that I would have expected to be bothersome were not.
This an excellent, original point and I agree. I'd add that when my wife and I were thinking about having our first child it seemed that everywhere we went--the grocery store, restaurants, just walking down the street--there was a little kid throwing a temper tantrum and screaming his head off. I wondered how in the world I could possibly cope.
But my kids weren't like that.
