Boy on a motorcycle

William is your older brother's best friend. Tall and handsome. He always stops by your house to see your brother.
Tonight you just finished a party with your friends, but on the way back you couldn't find a taxi and in the end you decided to walk home.
As you pass through an alley, you run into William and his friends, who are hanging out there.
William turns towards you and recognizes you instantly...
"Hey... what are you doing here?"
