the other one loose

I am pretty much lack of restraint
personified. I decided
a long time ago
restraint didn't work.
It just made me say nothing,
to think before I spoke. I can't
do both at the same time, and
doing the one first made the second
not occur. Irrelevant, by the time
I'd worked it out. I had to do
something, though, since my mouth
had a mind of its own. So
I decided to make WHAT I MEAN
a shining fountain of molten light
streaming up into the heavens
and showering down as cooled trinkets!
A canny decision, as it turns out. I was torn
at the time you see. Should I make WHAT I MEAN
a shining fountain of molten light
streaming up into the heavens
and showering down as cooled trinkets? Or
should I make it a fierce and hairy sort
of horse-dragon with horns sticking out of it
blowing reveille all the time, all rending teeth
and gnashing claws and beating wings? I think
I chose wisely. But sometimes I let the other one
loose too
