Behaviours in the train

I saw someone sitting on the floor of the train. This triggered me to blog about behaviours in the train. I cannot tolerate people who do not give way to passengers who are alightling, people who push others without apologizing, people who like to be love birds on train (oblivious to the surrounding), people who like to talk and laugh laughly in the train (sometimes I am also guilty of that) and people who do not give seats to elderly/young children/ pregnant lady.
