All I need is a wee

You shout out my name
The volume makes my ears ring
Unable to think.
You shout it again
This time louder and with force
“I’m doing a wee”
I shout down the stairs
“I just need a wee, hang on”
You shout out my name
It sounds like you're ready to explode
I walk back down the stairs
Feeling anger bubbling away.
"You knew I was going to do a wee,
Why do you have to shout like that?"
"I want plaits in my hair today"
You say
And I have to remember, you are 3 
Living in the moment
Is really what you do
And what people spend a whole life time
Remembering how to do it
But it's very hard to think that
When all I needed was a wee.
