Dh has some friends visiting, staying un a holiday home nearby. They came a day later than planned because the vomiting bug was doing its rounds in there house and the mum came down with it the day they were leaving. Now they are here the Gran has started vomiting. I feel bad but dh and i have said we are not meeting up atm because we dont want to catch this bug. Its our daughters birthday this weekend and we have a big party organised. All of us puking would be my worst nightmare. AIBU??
