Last week, I was listing in computer at ESL class. My friend who sat near me, she was reading the lessons in her computer. Suddenly, I heard someone call me:" Dung, can you help me?"
I took off my headphones and put them on the table. And I went to my friend to help her.
Afterward, I came back my computer, and continued listening, but I didn't hear anything. I turn up the volume, but I still didn't hear anything. I turn up one more time, so no sound. I checked my headphone once more, and I realized my headphone were on the ears my friend. At that moment, my friend looked at me and we both realized, We are wearing each others' headphones! Just both burst out laughing.
