It's the personality that matters the most. A good teacher should be able to give students encouragement when they are down, help students deal with stress, and be patient when teenagers are growing into mature adults. To meet these requirements, the teacher him/herself must be a strong-minded grown-up first, which is not that easy. Maybe that's why a good teacher is indeed rare.

crowding = making a crowds To prevent crowding on the roads above, please take the subway.

If you call a person spotless, to me, it sounds like they have never committed a crime. "He's spotless. He's never even gotten a parking ticket'

Hello Simone We use the expression 'I'll see myself out." You might say this to your grandma if you don't want her to get out of her chair for example. This can also be used when you are very angry at someone and you don't want them to come to the door with you. You hear it a lot in dramas 😆
