When living life, it can get so engrossing, you may forget it is not a one way street. There are other people around you. They may behind , in front ,trying to pass by you, or coming from the opposite direction.
So what do you do? BE AWARE. Stay focused on your driving. Don't get intimidated by honking horns. Don't intimidate others with your horn either. It's OK to let other's overtake you. You can do the same,without endangering yourself.Some of these people you will see, everyday, some for a certain period, others never again. So do be courteous.
Bear in mind though, only ignorant people act like they own the road. The road belongs to no one.
