Wednesday 8/20/08 chicken pox???...

One of the neighbor kids across the street has something that looks like chicken pox. Her mom came over and showed it to me. She said that most of her kids, including this one, had already had chicken pox. Can people get it twice?My kids had it years ago. Can they get it again? It was very uncomfortable for them, they itched a lot. When they find out what it is, they will come back and tell us.
