If i hear just one more time, when i am asked what i do for a living,

"Wow! Does that mean you can read people's mind?"
or
"Hey, do you know what i am thinking now then?"
or
"Heh heh, are you going to come after me with a chopper in my shower?"

I am going to throw up on his/her lap and excuse myself politely after that.

Repeat after me...
Psy-Cho-Lo-Gist.
Psychologist.
Not Psychic.
Not Psycho.
Psychologist.

I don't read people's mind (like some cheap party trick).
I cannot, for the life of me, fathom what a simple mind (one who cannot differentiate between psychologist and psychic) like yours would be thinking about (i am so tempted to insert something rude here).
AND
I do not have a habit of chopping people up just because they make such duncical remarks (but oh yes, have i ever been tempted).

As to what do i really do as a psychologist... well, i shall leave that to another post when i am slightly more lucid and less livid.
