My brother's bday was last week and he turned 33. My parents are having dinner/cake at their house for him and it will just be my parents and siblings there. They only live 15 minutes away but I really don't feel like going...

-I'm 35 weeks pregnant & feeling antisocial

-Baby could come in 3-5 weeks and I have a lot I still want to get done.

-Over the next few weekends, I have two weddings to attend along with another event which takes up my weekend time.

-A couple of my brothers smoke...they do it outside but I still manage to come in contact with it each time I'm there.

-I'm vegetarian and would need to make and bring my own food over anyways.

Am I being unreasonable? Should I suck it up and go, or is it ok to stay home just because that's what I really feel like doing? Just need some outside opinions. Thanks ladies.

EDIT: This is not a reason for me not to go BUT he did not come to my bday brunch because he drank too much the night before and didn't want to get up in the morning... 😕
