One thing you should say more often is hello person I've never met here's a high five. You should say that because when you see someone shy or someone who has a rough life like someone bullying him you should help him make him feel more better. And in a school you should high five him or make him feel better because if you do he'll treat you how you want to be treated. One time in my life when there was a new student I made him feel welcome by giving him a high five and he became my friend.
Another thing you should say more often is I don't know because sometimes in your life you will think you are right about something but you also need to tell the truth by saying I don't know. If you think your right you might actually be wrong and one time someone told me if knew what to do because I was working on a math problem with a friend and he told him yes but then I tried but I was confused so I guessed over and over and it was still wrong until I finally had to go to lunch but I wished I had said I don't know
