"KTHXBI (1/10/2007 6:47:25 PM)
My son comitted suicide a few months ago, when I searched I found two things- a note and pot. He must have been high at time because all that was written on the note was "KTHXBI". Police have been trying to decipher it's meaning, if it has one. Drugs have only brought sorrow and confusion to my family."

doesnt it just say ka tx bi as in ok thanks bye?

edit: I reread what I wrote and it might not make sense
