...unless he's said/done something you aren't sharing, it doesn't sound like he's cracking on to you or anything?

isn't it altogether possible that he's just lonely, and you're a friendly face? can't imagine he'd be having too many other ppl who would chat to him during the day, and who knows what his situation is like at home?

i used to have a coffee with the cleaner when i worked in a hospital every thursday around morning tea time. she was such a great lady and i was glad for the conversation, but i also know it meant a lot to her because work was all she had.
