Background: DH and I aren't at all close to BIL and SIL. DH and BIL speak on the phone for half hour every couple of months and no other contact.
BIL and SIL had a kid nearly 3 years ago, asked DH to be a godparent and he said yes because he thought it'd create a rift between him and his parents if he didn't.
So, we trekked three hours to their house for this Christening where BIL and SIL were very rude to us- didn't say hello to us, no thanks for the money, no small-talk.
Now: BIL and SIL are having another kid and have been chatting with PILs about getting it Christened. They've said to PILs that they're thinking of asking me to be a Godparent. PILs seem to think this is a great idea. DH has said it'll be awkward if they ask me to be Godparent for me to say 'no'- what he basically means by this is that it'd keep the peace if I did this.
I've never been christened, I've never been to church, I don't believe in God, I think the idea of Christening a child is pathetic and outdated, I don't like BIL and SIL and I have no desire to give up even one day of my life to go to this thing let alone play some kind of part in it.
How anti-social is it to say 'no' to being a Godparent? Is it ridiculously uncommon for people to say 'no' to being a Godparent?
