My oldest son left for college last week. I have two other sons and it just amazes me how empty the house feels with just one gone. I never realized just how much space a kid takes in your life. I think I was a pretty good dad - the kid turned out great, but I have spent the last week walking around thinking "I should have done more of this and less of that". Kinda makes me realize what a jerk I was to my parents when I left home. Anyone else going through this now?
