See, spot, kill.

Rimi's friend: and if that wasn't enough, he complains about my cooking *all* the time!
Rimi (incredulously): X complains about other people's cooking?
Rimi's friend: my point exactly.
Rimi: well, this gives me hope. I have been meaning to write a critique of nuclear physics for some time now.

Rimi's friend's annoying flatmate, who had been 'reading' the same page of the newspaper for the last fifteen minutes, decided to give up the pretence and join in.

Annoying flatmate: oh, so you're a physicist?
Rimi: god, no! I wish I were!
Ann. flatmate (shrewdly): so, you want to criticise nuclear physics without actually being a nuclear physics person.
Rimi (complacently): quite right.
Ann. F: and you don't think that is unethical?
Rimi's friend (with an exaggerated sigh): Ann, Rimi was only joking about...
Ann. F: but she isn't a physicist!
Rimi's friend: that's exactly the damn point!
Ann. F (in tones of superior astonishment): you mean to say it is 'the point' for non-scientists to criticise science??? You are going to encourage her to do this?
Rimi: (lets slip involuntary giggle)

My friend set down her enormous cup of latte carefully on top of Ann. F's shiny new copy of a bestselling lifestyle book, and looked at him directly.

Rimi's friend: Ann, I'm sorry. Obviously we haven't been clear enough for a mixed audience... we thought this was a private conversation. Rimi here was suprised that X criticised my cooking, given that he burns water. Her statement about critiquing--not criticising--nuclear physics was an... is allegory right, Rimi? [Rimi indicates she hasn't a clue] Anyway, it was a joke. All right?
Ann. F (getting up to go): anyway, I don't think anyone would have let a non-science person publish a criticism of physics.

A brief pause, while we hear the door open and close.

Rimi's friend (swallowing a hearty sip of coffee): he is moving to Chicago next month. Thank god!
Rimi: new job? Partner? Family?
Rimi's friend: do I care?
Rimi: good point.
