i love my swingset

When I was a little kid
(I'm a very big kid now,
I'm six and a half)
Daddy and Grandpa built me a swing set!
It's in my backyard, and when Megan came over
we would go outside and play on it.
But now, Megan has moved away
and my Daddy doesn't build me anything.
Daddy goes downstairs a lot
when Mommy is busy
so now nobody plays with me at all.
I tried to get Ben to come outside and play
but he doesn't like to leave the house,
not when daddy is home.
He did once, but I heard something

CRASH

from inside the house.
Ben ran inside, but I just got up and sat
in the wildflowers.
What was that sound?
