Beef Stew Mistake

I messed up what was undoubtedly a great recipe. My stew turned into a meat and veggies mixture that needed to be served with rice. The problem? Cati. It was all her fault. I got to playing with her and kind of, sort of forgot I was making dinner. By the time I remembered all the liquid was cooked out of my stew. It was still good though. The meat was so tender it barely needed a fork to be pulled apart. The veggies were so soft that I felt I could eat veggies cooked this way with every single meal. The next time I make this (there will be a next time) I don't know if I'd be able to stop myself from making the same mistake.
