Why would one need an emergency drywall patch kit in every room?

i have an emergency traveling toolbox that almost always has something useful inside. I started with the usual: screw drivers, pliers, adjustable wrench, hex keys, small multimeter, ruler, etc. The kit is packed in a small toolbox that can be carried in one hand. This kit started years ago with a very small assortment. If I need a missing tool three times, I’d add this permanently. At this point the toolbox is a great match for the types of emergencies that are thrown my way.
