The roller coaster

You really don't know which way it's gonna go
The tides up and then it's low
One minute the sky is full of stars
The next your stuck in the midst of the cars
He says yes but later says no
two goods then two bads in a row
With good news you celebrate
then you slip from love to hate
The roller coaster rolls inside
It's you that took this ride
The line was long and you did wait
Don't complain, it's a chosen fate
So when the next good news arrives
Hold on tight the coaster dives
Just the same for when it's bad
Something comes to move the sad
Get off the ride and watch the show
Then remember when next time you go
