AIBU, I have been asked by a close friend to host a party in my house for them. I'll be 9 months pregnant by the day of the party and I'm already tired all the time but I don't feel like I can say no. I would have thought that some consideration would have been given to the fact I'm pregnant before they even asked but they recently did helped me out with something which they pushed to do but was helpful (nothing on this scale) so now I feel obliged. My main concern about the whole thing is having a bunch of strangers in my house (20-30 people), the possibility of picking up a cold/flu and the deep clean that will have to happen after the event because tidying is not the same as cleaning. DH says he will manage the day and sort out all the cleaning after but I just don't feel comfortable with the whole thing. AIBU?
