tuna noodle casserole

i am making tuna noodle casserole for dinner tonight. it is in the oven right now. i had to call my sister for the recipe because she used to make it all the time when we were kids. she would get home at like midnight, high, and start making it, and then we would watch tv together and fight over what to watch. she liked b horror movies, and i liked the movies in which they talked a lot. she would never let me have any because i didnt help make it. and she would proceed to eat the whole thing by herself. and remain tall and thin our whole lives. according to her, the recipe includes an entire cup of mayonnaise. that is just too gross. on top of the cream of celery soup, butter and melted cheese! and she uses half and half. i skipped the mayo. i can't believe that's what i was eating all those years!
