Unspoken social rules that may help you

Unspoken social rules that may help you
Don't call someone more than twice continuously unless It's really urgent matter and if they don't pick up, wait until they return the call. They might be sleeping, sick, busy, or have something important going on.
If you borrow money from someone, return it, even before they ask for it.
Be nice and kind to waiters, cleaners, helpers, drivers, or anyone offering you a service, and treat them with the same respect you would give a manager or a CEO.
Always open the door for the person coming behind you. It doesn't matter if it is a guy or a girl, senior or junior.
If you take a taxi with a friend, and he/she paid now, you pay next time.
Never interrupt People talking. Wait until they finish then say what you want.
If you tease someone, and they don't seem to enjoy it, stop it and never do it again.
Say "thank you" when someone is helping you.
Don't break your promise or don't make one if you are not sure you can keep it.
When someone tells you a secret, take it with you to Your Grave, even if you wake up as enemies the next morning.
When someone shows you a photo on their phone, don't swipe left or right. You never know what is next.
Never talk about your riches in the midst of the poor. Similarly, don't talk about your children in the midst of the Barren.
