So I had a random man start chatting with me while I was waiting at the bus stop after I finished work. I politely let him chat and spent a few minutes listening to him (because I'm quiet and find it hard to say "I'm not that interested", I'm not sure if he was actually interested in trying to become friends or whether he chats to everyone. I have never seen him before today and don't know his name but he told me where he lives (I've forgot the address he said he lives at by now) and he was telling me where he used to live and about his health conditions and some other stuff as well (again, information dump so I forgot loads of what he said by now)

How can I tell if he's just a talkative person or whether he's actually interested in becoming friends?

For the record: I am not interested in getting in to a relationship with anyone
