I hung out with two different hobos in Prague, really chill people. One of them had worked in the UK for a bit as well as some other countries, he spoke a bunch of languages. He had this mouse pet called Stewart with him, he said he bought him from a pet store to make sure he had no diseases.
I met another one, I bought a liter beer at some shop and we drank it on the street, he spoke not the best english but it was ok. When I subtly asked him why he was on the street, he said he had mental problems, got this weird look on his face, I don't know if he was trying to say he was gay or pedo or what. Felt sorry for him.
