Some general politeness. Which I personally try to comply with.
Do not call anyone more than twice in a row. If he doesn't answer your call, it means he may be busy with something more important than your phone.
If you have borrowed something from someone, repay the loan before asking the other person. It reveals your dutifulness and character.
When someone invites you over for lunch or dinner, never order the expensive meal on the menu. If possible, ask them to order the food of their choice.
Do not create obstacles in the middle of someone's speech. Listen carefully first, then answer in time.
Thank someone for helping you. Express gratitude.
. When someone wants to show you a picture on their phone, don't swipe left or right. Because you don't know what's next. ...
. If a friend of yours tells you that he or she has an appointment with your doctor, never ask them about the reason for the appointment or the disease, just say, hope you get well soon. If they want to talk about it, they will tell you. Don't make them feel uncomfortable asking about their personal illness.
. Treat a cleaner in the office or on the street with as much respect as you give to the CEO of your office.
If you meet someone after a long time, do not ask their age and salary, of course if they do not want to talk about it.
Take off your sunglasses when talking to someone on the street. It's a sign of respect, moreover eye contact or eye contact is just as important as your statement
