I've been way too forgiving...
"A good general rule of thumb to follow is that most cooked foods should last four days when stored in an airtight container in the fridge within two hours of being cooked. It's also worth noting that the smell test isn't always and accurate way to tell if your leftovers go bad, so if you're ever in doubt, throw it away. That said, the four-day rule isn't universal and a few common leftovers won't usually make it all the way to four days. Cooked chicken and ground beef will only last three days, sandwiches with mayonnaise won't even make it a day, and most pasta with sauce can only make it two days. "
