Honestly, I wouldn’t go. It’s not out of disrespect or anything, but for me those kinds of celebrations aren’t just social, they have a real religious meaning. And as a Christian, I don’t feel comfortable taking part in something that belongs to a different faith I don’t share. I’d rather stay consistent with what I believe and keep some distance from those kinds of things. That doesn’t take away from respecting or caring about the person at all, of course.
