Noam's mum celebrated her birthday today for which everyone were really excited. All except the birthday girl, who's been doing everything she can to stop that number from leaking out. I don't know how you can hide your age from your friends, not from a moral point of view but from a logistic one. Between phones, emails and facebook I'd imagine hiding anything is pretty impossible. I guess owning a tranquilizer dart gun and a ninja outfit is a good start.
