Rosie has a cell phone.
She uses it a lot. Mostly to send Twitter updates.
She uses it so much, she runs out of battery power constantly.
And Tweets about it.
“Did you change the thing before we left?” I ask.
“Yes!” she shouts, and Tweets some more complains about low battery power.
So, I gave her my portable battery charger and bought a bigger one for myself.
“Here, take this.”
Now, she runs out of power on the phone AND the portable battery charger. Or she forgets the cord.
So, I bought earplugs. And I turn up my music loud.
