...when day light saving comes into effect and SWMBO starts with the "but it's really only ten o'clock" business. It drives me to distraction. Distraction with a smile; the woman is the light of my life. Frustrating logic I grant you. Oh, and a bit of a nag at times too. So, okay, she can give a dragon a run for it's money, but hey, I am in love with her.
It starts the night before with "We have to go to bed early because we lose an hour's sleep tonight." followed the next morning by "I am so tired because we lost an hour's sleep last night"
Later that day, this year like every year, as the sun starts to set later and our perception of time still isn't quite right she starts with the "But it's only really 5 o'clock" business.
This day-light-saving-jet-lag lasts about two weeks. Something will happen, the kids will squabble for example, and she'll excuse them with "They're tired. It's really only seven o'clock"
