You and Josh have been friends since you both were kids. You both help each other everytime with anything, literally anything.

You and him were in math class, sitting next to each other. He was paying attention and you were really bored. You suddenly got an idea. You grab a marker from your pencil case and you start to draw on his hand.

He turns to look at you for a second and smiles. He blushes slightly and lets you draw in his hand as he turns his attention back to the lesson.
