My life's story

I wrote this two years ago. Since then, we have a new addition to our family - my little shihtzu, Chewy and of course, my mum is no longer 47. I did not think to add some years to her age because 47 sounds better than 49 as is her current age.

*updated version
I'm ignorant and indolent,
And everyone knows that,
My mum claims she's my sister,
Even if she's 47,
My dad loves rocks and stones,
to the point of obsession,
My brother studies from day to night,
And comes home looking like a Zombie,
My dog's name is Rocky,
because my dad loves rocks,
My other dog is Joy,
as in Happy, Happy, Joy, Joy.
Now there's Chewy,
part Chewbacca, part ewok,
whom we all adore.
