My ds(11 going on 18) bless him is still on holidays (the six term thing) I went out tonight with some friends and left him in the capable hands of his favourite sitter. I dont get a signal at the pub so always leave the pub number at home in case of emergency,,, I left the pub at 10.30 and within 5 meters of being in signal my fone beeped twice both messages from my son's mobile....first message "I in bed" 2nd message "All ok" I had to remind myself how old he is. Nice that he cared to tell me though!!!
