Santa Claus?
5 yr-old: Is there a Santa Claus?
6-yr old: No there is no Santa Claus.
5 yr-old: How come?
6-yr old: Well...he was 99 years old last year, this year he turned 100, so he died!!
Shock and awe? Yup that's how my daughter revealed to my son that there's no Santa. So I asked her how she knew that there was no santa or how she knew. Well, I just do, was her response. Son still believes in santa, I think.
