Does she sound immature here?

My cousin is a really nice person but she appears to be obsessed with food, her pictures always involve lobsters and steaks and wines. I think it’s because she has put up with many difficult situations to get rich and food is her relaxation device, there is also a girl I hate who constantly slanders me and she loves to promote the lie I do not care about anything other than food.

I think normal people care more about human relationships, music, sports, architecture, nature, fishing trips, child care, video games, parties, entertainment, nature, gardening and home decorating, museums, galleries, pets and board games and religion and philanthropy.

I know my books and animal videos matter more to me than where I eat lunch or dinner.
