What are some unwritten social rules everyone should know?

1. Take care of your looks, it does matter, cherish every body-part, every feature of yours’. It's harsh but the world is abit kinder for pretty-confident people.
2. Don't avoid people arrogantly neither pay them attention more than they deserve. Know the limits.
3. Be kinder to every people you interact with, believe me it gets return in 10 folds but yeah don't do that in the greed of return.
4. Should never talk about someone's look , weight in negative sense , infornt or behind of them.
5. For girls, it's not nice to take favor or benefits from friend zone boys. Keeping a distance is respectful.
6. Don't bitch about your ex, at a given point of time, they were the reason of your happiness, respect that time.
7. Never try to agree with someone, when they say they don't like some thing, that you love/like. Just say: everybody has different choices and it's fine
8. For hindi speakers, when you met someone new , state them as “aap” not “tum” or “tu”.
9. For dates, if he pays for restaurant/Cafe, girls try to pay for uber(if he don't own a vehicle) . If he pays for movie tickets, girls try to buy popcorn.
10. For boys, pick up your girls for dates, try not to ask them to arrive alone at the place ( if you know them from prior, not the tinder date)…..like guys ,if you and your girl both are hosteller, try to pick and drop her from infornt of her hostel. It's attractive.
11. If you confessed your feelings to someone and it turns to be a “No” from them, don't ever beg saying, just give me a chance(it's not a fuc*ing audition). They said it clear what they wanted to say. (It's better you weep in your room for few hours and improve yourself rather than begging to them)
12. Don't show off, anything, anyone.
13. Try not to bring money in between relationships, whether it's friendship or any relationship. Keep your deals clear. If you're not so close friend, and didn't hit the rock bottom don't ask friends or relatives to lend money
14. Don't give advices, if not asked.
