Here’s the list of top unwritten rules in life everyone should know. If we all followed these rules, life would be a whole lot easier.
RULE #1
When you borrow someone’s car, return it with a full tank of gas, or at least fill it up more than what you got it as a way to saying thank you.
RULE #2
When someone shows you a picture on their phone, don’t swipe left or right . . . you don’t want to see something embarrassing.
RULE #3
Don’t break up with someone over text message, email or using a social networking site.
RULE #4
Always leave at least one buffer urinal between you and the sir next you. Never do this.
RULE #5
Be quiet when other people are asleep. That means more than not talking — not slamming doors, drawers, etc.
RULE #6
If you ask your friends for help with some house work, feed them as payment.
RULE #7
Chew with your mouth closed. No one needs to hear you crunching.
RULE #8
Don’t let your arguments escalate in public. If you feel you can’t control your language or volume then go somewhere else where to continue where other people won’t feel uncomfortable.
RULE #9
Always leave the last piece of something to the person who bought it, unless they really insist they won’t eat it.
RULE #10
In case you miss a call, drop a message as soon as possible if you’re unable to call them.
RULE #11
When you borrow money from a friend, pay them back as soon as possible. It doesn’t matter the amount, don’t assume they don’t need it, never make them ask you for it.
RULE #12
If you stay the night at someone’s house, make the bed before you leave, regardless if they plan to wash the blankets or not.
RULE #13
When someone else cooks for you, offer to help with the dishes.
RULE #14
If someone gives you space, or the right of way on the road, wave to them as a sign of thank you.
RULE #15
Don’t make plans with friends, or talk about plans with friends, in front of people who weren’t invited.
RULE #16
Don’t stop in the middle of a busy sidewalk or the entrance of a subway station. Source
