I'm surrounded by people who don't know how to say thank you, please, and excuse me. They also don't know the simple etiquettes. They fart at will, grab things that don't belong to them without asking, chew out loud with their mouth opened while eating, use profanity, and don't wash their hands after using the restroom.
Some of these guys have children. I wonder how they'll turn out when they're older.
A little bit of respect can go a long way in life.
