To get my feet wet in Puzzling here is a small riddle:
There is a message I must give you.
I, who was next in line,
who have left my brothers to come to your aid.
If you are not ready to heed me, I will wait.
Only do not let me fall before you do.
What am I?
I can be whatever colour you find me in.
I wait in one place, clinging on as long as I am able.
