CAN YOU GUESS THIS RIDDLE?

Only one color, but not one size,
Stuck at the bottom, yet easily flies,
Present in sun, but not in rain,
Doing no harm and feeling no pain. :D

Is it a shadow?

When I have food in hand, the office dog always follows me - in fact he generally just follows me, and I recire to him:

I have a little shadow that always follows me
And what can be the use of it is more than I can see!

I think you are too smart, Karen. I don't do well with things like this. Is she right, Jackie?

[jackiesdaisy1935]

Wow Karen, you are smart and quick and right. It is a shadow. :)
