Did you ever experience talking to someone you do not know at all?
It happened to me earlier today.
I was waiting for a jeepney outside our house and I noticed a man from afar who is waiting, too. He hailed the jeepney first. As soon as I was seated, I opened my bag to get my coins. The man said, "I'll pay for your fare." I swear I do not know the man nor have seen his face before. Just because I do not want to sound rude, I said "thank you" but the entire 10 minutes of riding the jeepney until I got off, I was trying to remember who is the generous man.
