The correct answer is: machine.
“Please” and “thank you” are the little courtesies by which we keep the machine of life oiled and running smoothly. Without these simple words, our interactions with others would be much more difficult and frustrating.
When we say “please,” we are asking for something in a polite way. This shows that we respect the other person and their time. When we say “thank you,” we are showing our appreciation for something that someone has done for us. This shows that we are grateful and that we value their kindness.
These small courtesies can make a big difference in our relationships with others. They can make us more likable and approachable, and they can help to create a more positive and productive environment.
