Don't ya just hate it when

Don't ya just hate it when you are thinking about something and it is soooo important.  You have to remember to tell someone something or do something.  It is first thing on your mind and you are so happy you remembered it.  AND THENnnnnnn you quickly forget it.  Something distracts you and it flies out of your head.  You remember it was important and that you really wanted to take action on it.  But it is just GONE!  Where do those things go?  Someplace along with the missing socks, scissors, roll of stamps or maybe the tweezers?
