3 Riddles
1. I am a protector.
I sit on a bridge.
One person can see right through me,
While others wonder what I hide.
What am I?
2. Every night I'm told what to do,
and each morning I do what I'm told.
Yet I still don't escape your scold.
What am I?
3. Each morning I appear
To lie at your feet,
On a bright sunny day
We're most likely to meet
All day I will follow
No matter how fast you run,
Yet I nearly perish
In the midday sun.
What am I?
