That sounds like very poor form, I'd be pretty upset about it too and, as delirium said, I'd probably make a passing comment about it so she knew how you felt.
Can I ask a question (of anyone), I'm not at all religious either but I thought god parents were someone you chose who would look after your children if something happened to you. I thought that was their actual role. Is that incorrect? Sorry, don't want to hijack the thread but am just genuinely curious as to what their actual role is, because I think I might have misunderstood. I always thought it was really weird that people chose non-couples because it seemed at odds with what I thought the role actually entailed, it makes more sense if I actually had it wrong all along!
