I think you probably need to ask your friend what she expects. :) Tatum's answer to your previous question is correct, but my family is not religious, and I still had a "godfather." My parents simply told me that if something bad happened to them (for example, if they died), then my godfather would take care of me and my sister. He was my dad's friend, so we visited him sometimes, but I think everything would have been the same even if he hadn't been our godfather. He was basically just our parents' good friend. Sometimes he gave us presents on holidays. I don't know if your friend is expecting something more, so maybe you should ask her and find out. :)

I'm Godmother to my niece. She's an adult now but the role in practice involved being a cool aunt and a friend. I would've been that anyway. The more serious aspect of the role was that I would've been responsible for raising my niece if anything had happened to her parents. That was understood. But for some people, it's really just an honourary role that doesn't really extend beyond the baptism. So I think you should thank your friend for the honour then have a chat to establish what her understanding is.

From my knowledge, being a godparent really isn’t a daunting task. It’s usually a close family friend that maybe the child can talk to if they don’t feel like they can talk to their parents, bring gifts during the holidays and birthdays. It’s like being the “cool aunt”.

Being a godparent is an honor more than anything. It’s basically your friend’s way of saying “hey I consider you like family.” There are some religious implications such as spiritually guiding your godchild, but that isn’t really that prevalent nowadays. The only thing I can think of is events like a Quinceañera and how there is a part with a Priest and the godparents, but if your godchild isn’t Hispanic then it isn’t something to worry about. The godparent thing is basically nothing more than an honor. In my family, my aunt is my godmother and she doesn’t treat me any different than any other aunt or uncle would. The only different is I refer to her as Nina (shortened for Godmother or Padrina in Spanish) sometimes although I use it almost interchangeable with Aunt and Tía. Basically, don’t worry about it.
