I do remember the college girlfriend that we let stay over with our son when they were doing A levels who I found out had a propensity to lie in, not unusual at that age I suppose, but my son had a Saturday job before he went off to university and had to get up about 7.44. On one occasion, he and girlfriend had been out the night before. I did say to him perhaps he could get her up to leave with him when he left for work at around 8.30, bearing in mind the station is 5 minutes away and he had to walk past it. My son asked if she could just lie in for a bit longer after he left, "OK" I said grudgingly thinking she'll be gone by 10 at the latest. We had to got out in the morning. That afternoon we had a painter decorator coming round to give us a quote, had forgotten about girlfriend, presumed she'd gone, hadn't checked as son's bedroom was up on the 3rd floor of our house. So I show painter into the rooms I wanted decorating including my son's, it's mid afternoon by now, we go into son's bedroom to discuss what we wanted done, we were talking away and became aware that the duvet was moving around of its own accord, out pops her head, it seems we'd woken her up, only 3pm frightfully tired apparently! My son did admit after they had broken up she was lazy, which didn't surprise me when I asked her if she was studying hard for finals, she said "no I really don't want to stress myself" She didn't get the grades she wanted for her initial choice of uni. Anyway, I gather she's a chilled out yoga teacher in Australia now. So hopefully not stressed at all and getting plenty of sleep
