If you can only take your parents in small doses, will you be surprised when your children can only take you in small doses?

jca recently asked a question about whether people get along with their parents. Of course people run the gamit of not talking to their parents to being very close with their parents, with various levels of tolerance inbetween.

This made me wonder a couple of things:

Do most people think it is normal to have parents that can be frustrating or annoying? Or, do you think most people get along with their parents very well?

And, back to the original quesion at the top, if you find your own parents annoying, are you surprised your kids find you annoying, did you expect it to be very different for you as a parent?
