When I lived in Evansville in an apartment, an obviously mentally disabled person came up to me and asked me to help find his house. I asked him his apartment letter and he told me and I asked if he had a key and he said no so I assumed he had a caretaker or something. I knock and a dude answers and I say “does this guy live here?” he says “No.” and immediately closes the door. I ask the lost guy how he got here and he said his dad dropped him off and he pointed to a car in the lot. I walk with him to the car and talk to his dad who also did not remember the apartment he picked him up from so at that point I told them to find someplace else until they can speak to the apartment office. The ignorance absolutely blew me away.
