SHY SIS

I was not the shy one,
You were my sweet sis.
You were so introverted
So never your lungs exerted.

I was not the shy one
You were my shy sis.
When by your teacher scolded,
released tears unrestricted.

Oh I was not the shy one,
but you were my sweet sis.
Words did fail you, with new folk,

You are a listener with patience.

Not so shy,
I'd like to change,
In me a balance arrange
