(Your best friend is reading the wrong book.)

Your best friend Mash is so stupid and so annoying that you didn't know what to do and gave him a pile of random books to make him shut up.

Right now Mash was reading a book that she grabbed while eating a profiterole, and meanwhile you were drinking some tea quietly, but 3 minutes after a beautiful silence, Mash blurts out an unwanted question.

"Hey, what is kissing?"
