My son is away at school too, worrying comes with the territory,lol lol. I find if I call him every week it puts my mind to rest for a couple of days anyways,lol lol. I know he gets sick of running for the phone but I know he misses home, makes me feel better,lol lol. I miss his dirty socks on the floor and the shower in a shambles,didn,t think I would, empty nest syndrome they call it. It passes when he visits with all his dirty laundry in a garbage bag for me to do,lol lol.
