15 things I have still tried to learn

Two months ago (I think)  there was an article on the headline of Yahoo!. I'm not a child, technically...

However, my behaviors are still like a kid sometimes. After finishing reading the article, I counted up how many manners out of 25 I know and carry out. I picked 15 manners from the article as follows (parentheses are my comments):

1. Do not interrupt grown-ups who are speaking with each other unless there is an emergency. They will notice you and respond when they are finished talking. (Sometimes I cannot wait and help but interrupting until someone finishes talking...It's not good, though.)
2. If you do need to get somebody's attention right away, the phrase "excuse me" is the most polite way for you to enter the conversation. (I don't say "excuse me." Well, I suddenly speak or say a hesitation. Just because I didn't know this manner...)
3. When you have any doubt about doing something, ask permission first. It can save you from many hours of grief later. (I see. I forget to ask any permission, and should do it.)
4. The world is not interested in what you dislike. Keep negative opinions to yourself, or between you and your friends, and out of earshot of adults. (I know, but it's very difficult not to utter what I dislike.)
5. When people ask you how you are, tell them and then ask them how they are. (I have to follow this rule next time.)
6. When you have spent time at your friend's house remember to thank his or her parents for having you over and for the good time you had. (I know it's important, but sometimes I don't do that...)
7. When you make a phone call, introduce yourself first and then ask if you can speak with the person you are calling. (It's dependent on situations because now we can know who is calling through the display on a cell phone and phone. But, I should introduce myself first anytime. It's more appropriate way.) 
8. Be appreciative and say "thank you" for any gift you receive. In the age of e-mail, a handwritten thank-you note can have a powerful effect. (Sending a handwritten thank-you latter is a fabulous way to convey our appreciation. My mother always does send a handwritten thank-you letter, but I don't...Really I should.)
9. Never use foul language in front of adults. Grown-ups already know all those words, and they find them boring and unpleasant.
10. Do not make fun of anyone for any reason. Teasing shows others you are weak, and ganging up on someone else is cruel. (OK...But I'm not sure to follow this manner.)
11. Even if a play or an assembly is boring, sit through it quietly and pretend that you are interested. The performers and presenters are doing their best. (Yes...But, pretending is my weak point because I'm naive, honestly(?).)
12. If you bump into somebody, immediately say "Excuse me." (Don't retort, of course.)
13. As you walk through a door, look to see if you can hold it open for someone else. (And, lady first!!)
14. If you come across a parent, a teacher, or a neighbor working on something, ask if you can help. If they say "yes," do so -- you may learn something new. (It's a good way to start a conversation with someone as well.)
15. When an adult asks you for a favor, do it without grumbling and with a smile. (Smile plays a significant role in giving good impression. At least, we shouldn't express Pan Am smile. When we are asked something, we should do it with smile with "crow's-feet," according to a speech by Guy Kawasaki.)
