Son of a balloon man

Yes , son of a balloon man
It's my real identity
My father tries to make
children happy by selling
these colorful  balloons,
but they appear colorless to me.
In fact, I became scared when
they are not sold ,
no sale means no food to eat .

The kids over there must
have thought how lucky I am ,
that my father is a balloon man.
I can play with balloons whenever I want .
Honestly, I never got a
Chance to play with them ,
to run with them .
They never amazed me !

Sometimes I ask my father,
"Why I am not allowed to play
like other kids playing in that garden ? "
My father answered,
"You are too mature for all this "
Matured ? What does it mean?
Must be a word , I will learn it
Once I will join the school
