Two

My brother and me
Share a birthday, May 14
We live our own lives separately
But we're always there
My brother and me
Get a long but sometimes disagree
I call him names and then I feel shitty
But I always care
And it's not hard to tell who's who
He's taller by an inch or
My brother and me
Think about things differently
We got two brains and two bodies
But the same last name
