I laid awake last night thinking

I laid awake last night thinking....
I still question the grammar of that statement - Susan Holwerda....help me out
Bob and Lisa are in the midst of a couple of tough weeks. But they know their general mileage, they know most of the elevations, they know there is a break in sight, they know there will be a meal waiting for them when they get back to camp and they have a pillow to lay their heads on at night.
People who live in the cycle of poverty have no map of where there days or weeks are going, they don't know where their highs and lows will be, they don't have any idea when the days of hunger and despair will end.
Just a thought to, help me once again, put things in perspective.
