Coping with the criticism.

Just curious as to how everyone handles the inevitable criticism that people seem to give young women TTC. It seems like you can't win for losing! If I tell people I'm not trying, they say "oh you don't want to wait too long, the clock is ticking." However if I say (truthfully) that I'm TTC, people say "oh you're so young, you'll never be able to handle it." How do you ladies cope with that?
