This article talks about how to reply to humor.

I'm here. Now that I'm here, I have to say something! Just a few words! If I don't say something! I'm sorry, since I have to say a few words! Then you must talk ~ so I decided that a few words might change everything! Maybe these words I said won't change anything! But! Nothing can change even if I say a few words! But I still want to say a few words I want to say! If I don't say what I want to say! Then, I came here without saying what I want to say ~ ~ First of all, I'm sorry for myself if I don't say what I want to say! Actually, I won't say these words! It's a waste of what I said above! In the end, I summed it up! ! ! I'm just saying something casually.
