"Do you like my hat?" Yes: "Of course you do, it's incredible" No: "Get out of my sight you disgusting little piece of filth, the nerve of you, to insult MY hat, my MAGNIFICENT hat, my absolutely magnificent HAT." (If you talk again:) If you said yes before: "Glad to see another hat lover, by which I mean a lover of MY hat specifically" If you said no before: "Get out of my sight" (If this is too complicated than you can just have him assume that you say yes and just say the same thing every time like:) "Do you like my hat?" "Of course you do, its incredible" and same thing when you talk to him again.
