A girl

I've just listened to a gushy message on my ansaphone from my MIL telling my husband that his cousin has found out she's having a girl and how lovely it is after all these boys to finally get a girl. All these boys? Weird seen as on my husbands side of the family there is him and his brother who has no children and his cousin - so 'all these boys' is actually singular one boy- mine. Of course the last time the news of a little girl joining that side of the family they were all talking about my girl. Apparently after speaking with his mum my husband felt the need to add that his cousin would have much preferred a boy. Why on this occasion could he not just keep his mouth shut
