Simple Question 05 Poem by Kim Barney

My brother and I are the same age.*
We're reading a book, and on the same page.
We like the same sports and dress just alike,
but have to take turns when riding our bike.

We have the same father and have the same mother.
I love him so much; he's my only brother.
We've had few disappointments and so many wins.
Can you possibly explain how we are not twins?

*(Dear reader, let me also say
that we were born on the same day,
same month, same year.
Is that more clear?)
