I was careless about leaving containers of old food out until they rotted.
That's gross. Does carelessness in your opinion sometimes cause problems?
Yes, because if I'm not careful I always make mistakes.
Yes, you shouldn't leave food out like that. Be sure to place it inside the fridge.
Wth does that have to do with me? I get blamed for everything.
You said you were careless so you do deserve some blame. Just make sure your food gets to the right place after you are done.
