I know why he's upset. Men have very few outlets. The few they do have, for some reason women can't leave them untouched and uninterrupted. His reaction is justified as his peace was disrupted. Maybe his ONLY quiet space. So yeah, he was well within his right.
my least favorite thing about serving is at the end of the night I will put up all the chairs surrounding my last table and they still won’t fucking leave
your partner coming to you about something you’re doing wrong isn’t a personal attack. It’s a sign they value the relationship – it's a heads up. You communicate, you fix it, you stay. That's emotional maturity. That's love.
