You were going home after being at your friends house. But then it started raining so you seek shelter at an abandoned building. You didnt have an umbrella and you didnt want to soaked so you decided to wait until it stopped

You suddenly hear someone honk at you. You turn around and see a black BMW and you know who it is

"Get it." It was your brothers best friend, Alex, you quickly ran to his car and sat at the passengers seat.

Why would he do this for you?
