I'm an older bride, and my father has passed. My cousin is going to stand in for him at my wedding in October. I know I have to get the flower girl and my matron of honor gifts. Should I also get my cousin one? He is fairly well off, and I am relatively poor. I know he won't hold anything against me. He's the nicest person on the planet (seriously, he is). But I'd like to do this right if I can... so is there a rule about this?
