Pil gender bias

Feeling so frustrated with my inlaws … when my husband and I broke the news that we were pregnant with #1, the first thing out my mil mouth is “hope that its a boy”. Omg!!! I felt so irritated then as I felt that no matter if its a girl or boy I will love them equally the same. Fast forward 20 weeks later, we confirmed that we were having a baby boy. And of course, pil were so happy they started clapping in a restaurant. Is it weird that I feel annoyed by their actions? In my mind, its if u want a boy then why not have another one yourself….
