I was staring at the HDB blocks whizzed past when I saw the senior man's reflection on the window. He was doing something...weird. I turned my head and looked at him. He was using a pincer to pluck some strands of hair from his chin (I won't call it a beard or a goatee as what he had didn't qualify for both). After plucking, he looked at his "bounty" before tossing it onto the floor. That's disgusting! I looked at him but he ignored me. It seemed that he was engrossed with those strands of hair under his chin. I looked away deciding that HDB flats were more interesting than a senior citizen's chin hair.
