There are many things that make me angry. For instance :
People without wearing a mask on a public transportation ,they spit on the floor also coughing without covering their mouth with a tissue,
making a loud noise in the midnight, talking loudly on a bus or a train ,when guaranteed days they escape to go outside etc...
In my opinion,this kind of people are very selfish ,they don't care about the other people feeling or lives and they are morallity questionable ,I am sure.
