I'm known to be quick, but not known to be noticed;I happen less often the more that you focus;When I happen I'm two things at once,And I happen thousands of times per day,Every day, every month.What am I?
It passes but you never hear it. Sometimes though, you think you feel it. You think you had it but it's gone. You want to stop it, but it moves on. You lose it, gain it, maybe fear it, but it goes on, forever on. What is it?
