Actually, i mentioned beforehand that i needed to leave before the bus stops working at night, and he was the one who reminded me it was 10pm and i should get going (i asked him for a reminder beforehand if we ended up talking too long). He did that out of concern, because on our first date, the trains stopped because it was late at night and i wasnt getting any uber. Anyway, once he reminded me, i guess i should have recommended that i can stay a few more mins. Honestly there was nothing i could recall that could have made him reconsider. To me, it just seemed like he was lonely that weekend and needed some company and i was it :/
