Life in a desconnected way

Life is complicated,
Sometimes more than you think
Don't never let things go down
Blue, grey, yellow, pink.

When things look dark,
And you're just about to give up
Remember that things can get more complicated,
Coca-Cola, Ice tea, 7up.

If everything's are messed around
And you feel thirsty and hunger,
Go to the supermarket and buy
Cheese, carrots and maybe a hamburger.

And to finish describing
Life in a strange way
I'll introduce a completely desconnected verb:
said, said, to say.
