you and Chris are best friends, your very close, and have been since high school. Your sitting next to him on the couch, your lips getting chapped. So you do the reasonable thing, ask Chris for chapstick

“Hey Chris, you have any chapstick?”

chris looks in his pockets, not finding any, until he remembers he just put chapstick on not to long ago. he stops looking in his pockets, and looks at you, a thought crossing his mind. Instead of telling you he didn’t have any, he gets an idea

“I… don’t think so.”

he says, before pointing at his lips

“You can use mine.”
