She phoned to say "When the baby is born I will come and help if you need me to, but there is a proviso - I will ONLY come and help if you actually need me there. Don't just think it would be nice for me to come because I'd rather come another time. It's not like I could do anything useful anyway. And to be honest this is your third baby so you probably know what you're doing. But I want you to know that if you actually need help I will come if you ask me to, as long as you're not asking because you think it would be nice for me to come".
So.
Wasn't that nice of her?
Yet somehow I don't have a warm, fuzzy feeling inside.
