Reality Check?

I know I just find one. Can you?

My different shades of reality are different by days
Some melo some bright
But dear sir do not loose your sense of reality it's priceless
If the little man on your shoulder tells you something is wrong
Then don't do it.
Say no.
The temptation is there but don't be afraid let the good Lord take the wheel
And maybe you afraid will be saved.
