I always chose to let my brother cut. Then, even if they were perfect halves, I still laughed like a maniac and acted like one piece was clearly better.
Ok, now try being the youngest of 6 when they all steal food off your plate. I eat like a speed champion. Also, i'm a girl so i had to put up with the "growing boy" one year older than me getting double my meat portion. He didn't even like meat and was a vegetarian by age 14. I have food issues.
I worked with a couple where the GF did that, bag of chips? No problem first separate by size them distribute between them she did that with everything bol of pasta of any kind ? same thing but she was a crazy bitch for more than just that.
