It's one of 'those' threads I'm afraid. We got to a campsite a couple of days ago, left the house at 5.30pm and went to bed at 10.30. DH went straight to bed, I asked if he'd peed in the hedge but he hadn't. I found out (after being married for 20+ years) that he only wees when he feels the urge to go and doesn't empty his bladder before bed/long journeys etc. I'm amazed that he doesn't, he's amazed that I do.
AIBU to think that you wee before bed?
