The other day, around 3 o'clock in the middle of the night, I was awakened by my wife, and I was surprised and got up.

She said that "the water supply to the he tank of the toilet is not stopped," and I was relieved first.

The connection between the float (plastic container containing air) for detecting the water level of the water tank in the toilet and the joint of the shutoff valve was poor, and the water supply could not be stopped.

The cause was the "aging deterioration of parts" of the joint part, but when the joint is removed and put on again, it will be repaired immediately.

I will fix it on the spot, but my family can't do that.

-----

So, from 3 o'clock in the middle of the night, my wife and I in the bathroom, began the lesson of fixing the water tank joint.

I could complete this work in one second, but my wife could not fit the joint again and again, and finally, she tries to fit it with force.

I thought "the joint part is broken on the way" and I stopped the work and decided to teach carefully again from the beginning.

As soon as I watched the shape of the joint, I could understand how the joint connected and I could understand the work process immediately.

In concretely,

The joint slant counterclockwise around 5 degrees, put the first hook, push the hook slightly weakly, and turning clockwise, locks naturally on the second .....

That was all, however, Even when I say this in language, she could not understand it. After all, she decided to "make power".

-----

I know well the phrase

"If you look at the shape of the parts, can you understand how to move it? "

is going to make human relations (couples, parents, friends) significantly worse.

In addition, this is a completely different from the person's ability and effort, etc. There is no responsibility for either my wife or me.

-----

This is called "sense".
