Answer:
I am wood that is neither hard straight or crooked
I carry you down a gentle stream.
I am ten little beans your look at everyday.
I belong to everyone. Sometimes make you happy sometimes make you sad. I will never end until the day you do.
I have a tongue, but cannot speak. I have a bed but cannot sleep. I have four legs but cannot walk. Yet I move as you do. What am I?
I am the kind of an ant that's good at math. What am I?
