How many e-mails do you get?

I got home from a 2 day P.T.A. convention last night and had almost 500 e-mails (not all of them were new) in my inbox! At what point do you just delete it all without looking and not feel guilty that you might have deleted something earth-shatteringly important? I guess I should have paid better attention in my "Effective Time Management" class yesterday.

Steve took the boys to the Stake overnight camp out last night. I heard a key in the door at about 11:00 p.m. They got up there and had the tent, but no poles or stakes. Oh well, they had a great time while they were there and Steve saved himself a backache!
