Everyone loves music but we have different favorite genres. Some loves heavy metal but I personally don't. Some loves rap but it leaves my tongue twisted. Some loves RNB but I don't have that soul. Some loves pop and I prefer that too.
I wonder what happens to a person with headphones on that sometimes they shout when they talk? Are they just carried away by the loud volume while listening to songs? In my OJT office, it happened lots of times that a person shouts or even sings too loud with headphones on. One of the employees had this habitual attitude of singing too loud when his headphones are on. He sings like it is the end of the world. Sometimes, his songs are full of feelings that it actually sounds funny when you hear him. He easily gets carried away of his emotions and let go of it by singing it loud. There was also a time when the environment of the office was silent and peaceful then sounded that voice that disrupted the mood. Late this afternoon, my workmate shouted to my other workwate. Well, the problem is that person wore his headphones and that he didn't that he was already loud.
When I put the headphones on, I'm always mindful with the volume of my voice. Maybe these people have disorders, I presume. I will name that disorder as, "The Headphone Attack Disorder" or "THAD". Laughs.
