To fetch my son and burning my pot

I was in the middle of heating up some stew for lunch, but my husband called and asked me to fetch our son, and I went out without turning off the stove! Imagine how careless that is. When I came back, the whole apartment stank with the odour of smoke. And all this is because my best pot burnt. That was the best pot I had. Now, I need to look at cookware reviews to get myself a new set of cookware now as most of my other pots and pans are also old and used already. Anyway, lucky my apartment wasn’t on fire. I definitely should be more careful next time.
