Eh, I could totally see that happening. I've had enough conversations with the extendedly-homeless to have lost my expectation that they'll seem normal by any stretch. Even the ones who I'm not sure were mentally I'll seem like they build a crazy persona as some kind of defense mechanism or something. One very friendly hitchhiker I picked up shouted "I'm a Beatle" while waving as I pulled away. A very old lady I gave some food thanked me by saying "Bless you! L-O-L; B-R-B; you and your family!" The truly homeless, who have been so for a long time, usually did not get that way as normal people; and even if they were they don't stay that way. It's a very hard life.
