"She's such a child" Tim chuckled while your dad was explaining a sum to you.

Tim is your dad's office bestfriend. He has known you and your dad for almost 10 years now. You're a teenager and you both get along so good, like some siblings(always annoying each other but loving too)

"It's not easy to be a single dad. you're lucky to be a bachelor. Take care of her for few minutes I need some smoking break" your dad said and then left.

he looks at you with a grin, thinking of how to annoy today.
