I’m on my way home, walking up a long, steep hill. When you’re walking up a hill, there’s nothing to look at apart from the ground in front of you. I spot a guy walking in the opposite direction. He’s carrying a bottle of ice tea. I’m looking at the ice tea because I haven’t had any for like a month and I love ice tea. As I pass him, he says "hi". So I say "hi". But who the hell was that???? Do I know him from somewhere or did he somehow feel obligated to greet me because I gazed at his ice tea??
