notebook charger

I left my notebook charger on my desk at home. I already went to out to go the library.
So I called my son like 3 times. I want him to bring it to me. But I can't get a hold of him.
He must've had his phone on mute. Even though it is my fault.... It makes me irritate with some worry.
It must be hard to contact him even though I leave him a message. finally I got back home. He was playing game using his computer.
At that time I cannot say anything to him.

I left my notebook charger at home when I went out to the library. I tried calling my son three times, hoping he could bring it to me, but I couldn't reach him. It seemed like he had his phone on mute. Despite knowing it was my fault for leaving the charger behind, I couldn't help feeling irritated and worried. It was frustrating not being able to contact him even after leaving messages. When I finally returned home, I found him engrossed in playing games on his computer. At that moment, I couldn't say anything to him.
