Never make fun of someone else's laugh — be it how they sound or how they look. Laughing is the most natural expression of joy and happiness, and for someone to feel self-conscious about that because of other people's comments is so brutal.

For buses/trains/any other public transportation, let people exit first before you get on.

Don't say s**t about someone's appearance if it can't be fixed in less than 30 seconds. Spinach in someone's teeth? Let a homie know. Body type? Bad haircut? Worn-out clothes? Don't need to mention it.

Don’t ever say ‘oh, you’ve only got one child. That must be so lonely for them.’ Because maybe that person tried for years to have that one child, maybe they chose one for good reasons, maybe that had another child that died that you don’t know about. Or, maybe it’s none of your business how many children people have. Actually, it’s definitely not your business. So, shhhhh.

Don’t leave your shopping cart in the middle of the grocery aisle!

Do not swipe left or right if someone shows you a photo on their phone.

Don't propose at someone else's wedding.

Be kind to people who are working: food staff, medical staff, etc. Don’t take your bad day out on someone else.

Don't cook fish in the office kitchen

Buy a plunger before you need a plunger.

If you're borrowing it for a third time, you need one of your own.

Leave it in a better condition than you found it.

Don’t put your music on speakers when in a public space. It’s not like everyone wants the same genre or was in the mood for music. Get your headphones.

Don’t mess up an apology with an excuse.

Don't start drama at a funeral.

Don't let friends drive drunk. Maybe offer to get an uber or something for strangers, too, if you can

When driving a car, dont be nice, be predictable. People being nice leads to a s**tload of accidents.

Chew with your mouth closed. Shocks me how many adults i see chewing with their mouth open.

I have two: 1. do not wear perfume or cologne if you’re getting on an airplane. 2. do not use speaker phone or play videos on your phone without headphones in public places. Especially in public transit.

Announce your visits. You can't be offended that nobody is home when you decide to drop by at random. Plus it's super unfair to the host since it gives no time to prepare anything and they might have to drop everything they were just doing just to entertain you or cancel their plans.

If you have to cancel on a friend, it should be your responsibility to reschedule.

Don't look through the f**king gap of bathroom stalls.

If you borrow someone's car, fill up the tank before you return it.

There was only 1 rule in my house growing up...do not wake anyone up. My parents worked shift work. Its amaZing to me now how many people don't respect sleep.

Always ask if a dog is friendly. You never know what kind of weird behavior things a dog can have, even when they appear friendly at first. I had a dog who would be fine until someone bent down to pet him. He was very protective and nearly bit a few people. I'd they has asked first we could have told them that he doesn't like being pet by strangers. I would hate to have to put my dog down because you are an idiot around animals.

Don't talk to anyone at the urinal.

Turn down your bass! Be more considerate of your neighbors in apartment complexes. I'm tired of people sitting outside my window in their car with their bass on full blast...at 2-3am! ((That's why I'm awake right now.)) I'm also greatly annoyed at my neighbors turning up their music (bass) to the point where it's rattling things on my walls. After getting multiple complaints you know it's a problem thus are choosing to be bad neighbors. *Also they have a lot of small children who should definitely be asleep but of course arent.

Don't ask for something if the person only has one left (gum, cigarette, piece of cake, etc.).

If someone asks you a question, finish what you’re saying with, “what about you?” Enjoy noticing how many people actually don’t do this.

Stand up when you shake someone's hand.

If someone whispers, you whisper back.

Pee first. No matter what it is, pee first.
