What Is It?

A stretch
A how high
A “Hi”
Could be a reach
for the sky (I suppose)
A superhero pose
The hurling (of an old boot)
An unacceptable salute
(don’t mention the war)
A wave (to the sun)
A “I’m so full of energy”
(and so young!)
A quick stick throw
(for an invisible dog)
A show of strength
An arm(’s length)
