have you ever been to a place where you stand there alone and you feel the fresh air passing by?
but then come a person stand by your side, and give some energy towards you and the environment...and if it's positive, then you will feel like the environment is still nice, but then if it's negative then you feel like the environment has been polluted...
so you start to have feelings that the air is dirty, smoke and harmful for your lungs...
then comes the suffocation....
so you try your best to stay in that kind of environment...you wear masks...change...
