Tilt of an Umbrella

Just like any other day, I got off work and was heading out of the subway station. But as I reached the exit, I noticed people coming down holding umbrellas. No way – Is it raining?! I hurried up the stairs toward the exit, and sure enough, it was pouring outside! What do I do now? I thought about buying an umbrella at the convenience store and walking home, but the store and my place are so close that it felt unnecessary… As I stood there hesitating, a voice came from behind me. “You don’t seem to have an umbrella. If it’s alright with you, would you like me to walk you home under mine?”
