The Perfect Word

I hate when you are on a roll. The words seem to be flying across the page. Then all of a sudden you can't find the word you are looking for. You can think of the meaning, words close to it, yet not the one word that you are looking for. So then you change the wording to fit someting else into its place. Then as you a laying in bed almost asleep that one word you spent half the day looking for pops into your head. Do you just leave it be or do you get up turn your computer on and change it. Sometimes it happens while you are having a conversation with some one. Have you ever called your friend up in the middle of the night just to say, "Hey, I remembered the word i was looking for."
