-When you aren't even trying and you find Danny glasses at a duty free shop in Washington (after leaving Canada).
-When you constently talk about wether Stella is good with Mac, or Horatio.
-When you constently come up with ideas on how to figure Adam Ross as a CSI, and then screw up the story
-When you write so much about Mac and Stella, you forgot the other names of the CSI's... (yes, I forgot Danny, Lindsay, Sheldon, and Sid's names once... it was very sad)
-WHen you watch "Snow Day", "Consequences", and "Some Buried Bones" so many times, you can replay them in your head word for word, and when you watch them with friends, you know when not to look, and bury your head in your arms. (I did that with Some Buried Bones. I hate it when Reed gets beat up.)
-When you listen to the song "Big Yellow Taxi" by The Counting Crows and Vanessa Carlton, and swear never to go to New York City and get in a yellow cab, EVER! Or swear never to get in a cab anywhere, for the remander of CSI:New York's lifetime (or my own... The Taxi Cab Killer will forever be on my mind... and Reed...)
Much more...
