Sorry I didn’t ….

I was home with my newborn when the doorbell rang, right in the middle of pumping.

I never answer it, so I just kept going. 5 minutes later, I heard a stranger talking to my husband downstairs. Then he stormed up the stairs, grabbed the baby, and said, “Sorry, I didn’t know they were coming!”

I’m like, “What? Who is it?” and he explains that his boss and his wife are at the door with a baby gift. I respond with “Okay” since I’m still attached to the pump machine. I finish up, then head to the bathroom to put on lotion. A couple of minutes later, my husband comes back upstairs, visibly upset, because I didn’t come down to greet them and accept their gift.
I told him I didn’t realize I needed to or that they were staying. He says it was very rude of me and that I’m a jerk for, first, not answering the door and, second, not coming down after he told me. He said they were asking him where I was and what I was doing, which made things awkward for him.
