Rant alert! I really just want to smack my sister right now she has been giving me an attitude and I cook for my family and she keeps telling me she is not eating because she's on a diet but all she eats all day is hot cheetos and pizza bites and then ask me why do we always have to eat meat. she has been really getting on my nerves so I've been trying to stay away from her as much as I can right now.
