My poor sister in law...

So my sister in law is 9 weeks behind me. And she just found out shes having a girl!! She just told me today that her boyfriend is upset cause he wanted a boy. I get it gender disappointment. Its one thing to be upset about it. Its another thing to treat your girlfriend like crap cause you're not getting what you wanted. They dont live together, so he normally visits during the week. She said, he hasnt visited all week, barely spoke to her since they found out and when he did come over he had a crappy attitude and left right when he got up. Im sorry that you're acting like a 12 year old but get over it. Dont treat the mother of your child like crap because you're not happy because you dont get a boy to go fishing with. You can still take your daughter fishing! I just dont understand how someone who's going to have a little bundle of joy, no matter the gender, can treat the mother of the child like that. You're going to be a father! Thats the best reward anyone can have! Okay, rant over.
