Comfort food is great. It's something familiar to fall back on when you're feeling down. Comfort foods full of memories of birthdays or Fourth of Julys or Christmases or even just times in your life. Like you remember eating grape popsicles a lot when you were little. Or for every birthday party growing up you always had Cheetos.
Comfort foods comfort us because they're memories brought back to life. Memories of parties or conversations or sleepovers you can never relive, but you can always go back and eat your favorite food :)
