How to reply to a boy's "touch on the head" in a witty and humorous way during chat?

"Touch your head" means to like, be close to, and dote on; at least, it doesn't mean you hate it.

But I think this like can be divided into two situations. One is what we usually think of as the love between lovers; the other is similar to the love between brothers and sisters. Boys completely treat girls as their own sisters, regardless of romance.

So I think that if a boy "touches his head" during a chat, a girl doesn't need to make her heart beat like a deer every time; If your face is red, your ears are red, and your heartbeat is racing, isn’t it too unreasonable?

So, if you are not interested in a boy, and you see him touching his head, you might as well reply directly, "I'm going to bed, I have to go to work tomorrow"; then, add "goodbye" action.

Simple and neat.
