Balloon

I'm like a balloon,

I could vary well be gone soon.

You let me go,

And I start to float away.

There I go into the sky,

I seem to fly.

Better reach for the string,

And bring,

Me back in.

Not to long to grab,

That string of mine.

My string is short,

But it all depends,

On how strong my Helium is.

Reach now please,

I don't want to fly away you see.
