Hubby was more upset than I was

We had our 20 week ultrasound on Tuesday last week, I didn't want to find out our baby's sex but hubby did so he found out. On our way home he's like you're not finding out no matter how much you beg lol if you do really want to know then I might write up a contract so that you can't get angry with me afterwards. We had to head back out and I was taking pics for my family since we just moved 3 provinces away and I'm looking at the leg pic thinking their legs are growing really well then I notice near the bum something. I start laughing cause the tech knew I didn't want to know and was really careful not to say anything and I say to hubby "so not sure if she meant to print this but I guess we're having a boy then eh?" He just gets upset like "fuck I should have looked at those more closely I'm so sorry" I'm like it's ok I knew right when we found out that I was pregnant that we were having a boy in my heart. Oh well so much for my surprise lol. Now we need to just figure out names 😫🤷‍♀️.
