1 - Don't call someone more than twice in a row. If she doesn't answer your call, assume she has something important to do.

2 - Return the borrowed money before the lender remembers or asks. Display your integrity and character. Same goes for umbrellas, pens and other items.

3 - Never order the expensive dish from the menu when someone offers you lunch or dinner.

4 - Don't ask embarrassing questions like: So you're not married yet? You don't have any kids? Why didn't you buy a house? or why didn't you buy a car? For goodness sake, it's not your problem.

5 - Always open the door for the person following you. Doesn't matter if male or female, old or young. It doesn't make you small to treat someone well in public.

6 - If you take a taxi with a friend and he pays, offer to pay next time.

7 - Respect the different shades. Remember what 6 is to you, will look like 9 to someone in front of you. Even a second opinion is good for an alternative.

8 - Never interrupt people when they're talking. Let them finish. Like they say, listen to them all and filter them all out.

9 - If you make fun of someone and it seems you don't like them, just stop and never do it again. Encourage someone else not to and show them how much you appreciate them.

10 - Say "thank you" when someone is helping you

11 - Praise is public, criticism is private.

12 - There is almost never reason to comment on someone’s weight. Just say "You're awesome". If a person wants to talk about losing weight, they will.

13 - When someone shows you a picture on your phone, don't swipe to the left or right. You never know what's coming next have respect

14 - If a friend tells you that you have a doctor's appointment, don't ask why? Just say: "I hope you're okay." Don't put them in the awkward position of having to tell you about their illness that is personal, if they want you to know, they will inform you without you asking.

15 - Treat the janitor, cleaner, bricklayer, garbage collector, homeless with the same respect as an entrepreneur, manager or employee. No one cares how much you can treat someone. But people will notice if you treat them with respect. Appearance is just appearance, be wise, reality is invisible to the eyes of most people in the world.

16 - If a person is talking to you directly, looking at your phone is rude.

17 - Never give advice until you're asked.

18 - When you meet someone after a long time, unless they want to talk about it, don't ask their age and salary.

19 - Take off your sunglasses if you're talking to someone on the street. This is a sign of respect. This is why eye contact is just as important as your speech.

20 - Never talk of wealth among the poor. Likewise, don't talk about children in the midst of women who can't have them
