Do you not already do this? I talk to every person on this planet the same way. Doesn’t matter if you’re rich, poor, known, unknown, or just plain weird. I’ll talk to anyone because most people will just talk normal to you. Some places in the world this doesn’t work all that well though since some cultures are more standoffish than us americans.
How do people make friends if you won’t talk to a stranger? A stranger is just a friend before they know you.
