Last night, my OH announces that he is going to bed at 10pm. I say goodnight, and I'll be up later. 10pm is too early for me.
5 minutes later I hear 'OLIVEEEEEEEEE bathrooms free'. I ignore him. I don't need the bathroom so why do I care?
A couple of minutes later 'OLIVE ITS BED TIME COME ON WHAT ARE YOU DOING'
Me: 'I'm not tired yet. I'll be up in a bit'
He is quite clearly getting irate about this and has started name calling so I go up to keep him quiet, I think I'll read my kindle in bed.
When I get into bed I apparently took far too long coming upstairs, and I've ruined his early night 
He then moans at me for using my phone to set the alarm. I didn't even bother using my kindle after that.
So do you think I AIBU? I always assumed that people went to bed when they were ready but perhaps couples do coincide bedtimes and I am being a dick about this? I need your wisdom MN!
