  • the fries are prepared, the carrots are not. I would much rather eat roasted carrots with seasonings than fries. don't get me wrong, I love fries, I'd choose them over the raw carrot any day. but it's not quite a fair fight to pit a food that's already cooked and ready to eat against raw food that doesn't even look washed yet.

    • Meanwhile, I think that plate of fries looks old and soggy, whereas the carrots do not. besides, raw carrot is fine, raw potato, not so much.
