I'm terribly sorry for troubling you so unnecessarily.

I know what you think, but I really am alright, so there isn't any need for you to be concerned about me, Sensei.

Rather than me, you really should worry about yourself more, Sensei.

At any rate, worrying about me is unneeded, so please think about your own issues, Sensei.

Look,

Isn't your face turning red?

Really, you'd better eat something
