DH does this sometimes, leaving everyone guessing where he is mid afternoon, only to find he's gone to bed for a 2.5 hrs nap.
His elderly dad is visiting us for the weekend as he's in our support bubble. DH took himself off to bed and was most disgruntled post-nap when I suggested that next time it would be helpful if he could let me know in advance that he'd be out of action for the afternoon, so I could make my own plans with his dad - even if it meant DH just shouting down the stairs to let me know on his way up to bed!
Pre-Covid, when we'd visit my parents he'd often slope off early to bed at 8.30pm/9pm without saying goodnight to anyone!
AIBU to think this is bad form?
