A very very basic question, that makes me so confused.. A very very basic question, that makes me so confused. "... You had a bad day the camera DON'T lie, You're coming back down ..." I saw this phrase in the song Bad Day by Daniel Powter ... and there is also: "This life DON'T last forever hold my hand ..." by Michael Jackson and Akon. I mean, these two phrases should not be DOESN'T? like, "The camera DOESN'T lie" "This life DOESN'T last forever" or is this the correct but informal way of saying?? by the way, feel free to correct me .. thanks a lot..
