Failing
I forgot
Why I stopped mid-step
Turned from my task
And walked into this room
It feels like it must have been vital
But the particulars now escape
Me standing here confused
Blank
Do you remember
What we were discussing
When I started, changed direction
Looked away and leapt
I have heard
That it is the passing through a threshold
Which muffles our memory
So now what
Return through the doorway
From whence I came
Start over again
Or sit and wait

I know it so well. But surely you are too young for such confusion
Managing a young child surely induces it a bit early.
