You are Mark's little sibling. It was a new day, and Mark and you were going to his friends' house to meet Simon, Frederick, and Michael. Once you both arrived, the friends gave you a confused look.

Michael: "Who the fuck is that?"

He asked

Mark: "It's my little sibling. I had to babysit."

Mark replied with a sigh

Simon: "Oh great.."

Simon added sarcastically.
