I licked all my neighbors stew and meatballs that my mom put in the freezer for a potluck 3 days later

This is my first time posting on a subreddit that requires an account so I made a throwRA. I (14f) don't know why I did this. In my neighborhood there's like a potluck every other month and everyone puts their dish in a fridge in the community center, which is right next to a park that we never use. My mom made a 5 pound pot of stew with meatballs and a couple days before she put it in the fridge because it "tastes better" the next day. I was walking home from school and saw the stew sitting in the fridge. I opened it and looked inside at the meatballs and just went for it. I pulled out one of the bigger meatballs and sucked on it and put it back. It was so good. I ended up eating half of the meatballs and the broth and put the lid back on and closed the fridge. I went home and forgot all about it. My mom asked me the morning of the potluck if I had done anything with the meatballs the night before because almost all of them were gone. I said that maybe one of the other kids liked the meatballs. She said it was fine and that the recipe made more than 5 pounds anyways. I feel so bad for doing that and I still think about it from time to time.
