How to say goodbye to friends in euphemistic language?

What I don't understand is: Why should teachers hate you?

There are good friends and bad friends. As the saying goes, "the feet are shorter and the inches are longer." Although she is not a good person, she will have a foothold. Maybe she can give you great comfort.

As a pair of friends, each other should cherish their friendship. You know her by fate, not by resentment (she is not a good person). It is impossible to "disturb" your friendship with gossip outside. Friendship is more important than money and love. One more friend and one more warmth.

My friends are also annoying, but I have many "bad" friends in my class, and I have learned a lot from them.

You should cherish it! Don't wipe away your beautiful rainbow with tears!

Think for yourself! I may not be right, but friends can't say no, no, and they are very annoying people.

Work hard! I hope your "this beautiful rainbow" can be "icing on the cake".
