How should a teacher hold an umbrella?

A student holds an umbrella for the teacher.
A passerby sees this and feels indignant, saying that teachers nowadays really lack professionalism.
The student then holds the umbrella over their own head.
Another passerby comments, "Kids these days really lack manners. How did the teacher teach them?"
Hearing this, the teacher takes the umbrella and helps the student hold it.
The passerby then says, "The child must have some background. This teacher is just flattering the powerful."
The teacher thinks, "Forget it, I'll just do it myself," and holds the umbrella for themselves.
Another passerby says, "The teacher really has no compassion. They have an umbrella and don't care about the student."
The teacher, helpless, sighs, "Alright, just put the umbrella away. No one needs it anymore."
Then another passerby says, "Look at this teacher and student. They have an umbrella but don't use it. The teacher is getting dumber, and the student is getting more clueless."
The teacher, anxious, simply holds the umbrella with the student hand-in-hand. The passerby whispers, "Look, teacher-student romance!!!"
