I'll preface this by saying I have good personal hygiene, so it's not that. I shower and bath regularly.
He usually works during the night but when he's off he does this every time.
I could be in the middle of a book or doing work on the laptop and he'll say "ill run your bath now"
I never ask him to. It's a nice gesture but not always convenient.
Sometimes I just don't want one, or want to be left to my book/tv programme/work. Maybe I'll only want a quick shower later on.
If you were in the middle of something and your DH tells you when to get a bath would you find it annoying?
