I Don't Want to Plug in Your Charger

I don't want to plug in your charger,
I only plugged it in yesterday.
Why do you live so precariously,
Always about to die?
The fact that you want plugging in again
Seems like a metaphor.  I have eaten a custard cream.
Make do with that, vicariously
I am at least as tired as you.
I am not going to expend more energy
Going up stairs, anyway,
I don't like the way you imply
I use up all yours, wasting the day,
Getting fat,
Sitting about Googling
Don't shut down or I will scream;
You have 4% remaining,
But you never ask what % have I.
