Seriously, we're both married to the same man!!!!
LOVE my DH. LOVE LOVE LOVE LOVE him. But his ability to focus on unimportant minutiae when something very important needs to be done absolutely astounds me. Yes, he too would be vacuuming the basement in preparation for a party on the main floor. Mine's been known to want to fix the leaky faucet in the master bathroom sink ten minutes before company is due for dinner instead of setting the table or something.
Adore him, but even my MIL and sister-in-law tell me that he has no really good sense of time and must-do priorities when it comes to family stuff like this, and he was like this even as a kid.
Take a deep breath. You aren't alone.
