What are the perfunctory, hot and cold?

The perfunctory and hot and cold are as follows:

1, get used to anyone's hot and cold, and look down on anyone's drifting away, so as to be strong.

2, cold and hot, far and near, light and thick, all with a normal heart, no love.

3. During this sad period, you can't help feeling sad, when what you want is contrary to reality, when your ideal can't be realized at all, and when your heart retreats day by day, who is wrong is wrong. Feelings are afraid of being defeated by reality, and bad temper will be defeated. What you want is clear, but you can't say it clearly. Many things only leave sadness, and time accumulates broken hearts.

4. People who are hot and cold to you must think of you when no one is with them. Even if he really likes you, his hot and cold attitude means that his feelings for you are vacillating and indecisive.

5. I was eaten by you, right? From high school to now, I am willing to be sentimental.
