Task saturation. It's windy, turbulent, your wife is uncomfortable and giving you looks. Someone cuts you off as you are landing, you go around. The field is busy and as you come back around for landing you're focusing about being unable to get your radio calls in. You land to the sounds of grating metal... Just one of 1000 scenarios.

As mentioned there are alarms already, but you can drown it out if sufficiently overloaded. Its best to recognize overload, take a deep breath and go back when calm.
