The atmosphere obviously began to become tense, and the audience said: "Can I go on again after I have been on the stage?" ”

The tutor looked around and said, "If there are no new people coming up, of course you can." I don't have to toss the time, and if you want to try again, give it to me. It's over in order, and I don't expect all three slots to be filled. ”

Almost as soon as the instructor finished speaking, the man who asked the question and his table mate stood up.

These two are obviously the same people as mentioned before, and they are running towards the stage at this moment.

I saw that the time was almost up and walked to the podium, the two men clearly stuck on the question of who would go first.

"I'll come first."

"I'm the one who asked if I could answer it."

"Unreasonable? First come, first served. ”

"You tell me this? Didn't I ask you to come up? ”

"What are you looking at?"

。。。。。。

The guru also saw this scene, stretched out his hand and said, "In order, from the left... ”

I said in the rear, "Both of you have been on stage, right?" Why don't you let me, who didn't go on first? ”

"What are you making a fuss about?"

"By the way, what are you doing with the two of us who arrived first?"

The scene became awkward for a while, and the tutor glanced at it and said, "Whoever makes any more noise will get out." ”

The two men fell silent in front of me.

"Discuss who will go first." The mentor said.

I raised my hand, and the instructor pointed at me and said, "You say." ”

"Both of them have been up, and I haven't been up yet. You also said before that if you haven't come up yet, just come up and talk about the last time you have been up, and the last time you have done it will be over. So my idea is that I'm going to go up first and let these two discuss it here. I can't do it anymore, and it's almost the same as what they've been talking about for so long. Then go on in their order. I said.

"Why?"

"yes, you're in the back. Aren't you cutting in line? ”

。。。

The tutor patted the microphone and said, "Okay, okay, don't argue." There's no one to say, isn't this one given? He goes first, and whoever of you is second or third weighs it yourself. ”

I went on stage with a smile, and the two of you in the audience were still chattering.

I didn't really have any ideas, but I didn't know why my father's words stuck in my head for a long time.

Sometimes, a thing can't be true. It's not the conditions that you look at, because the conditions you can make yourself.

I glanced at the toothbrush and thought, "How long do you think a toothbrush lasts?" ”

"Every three months."

"It's time to change in a month."

"Hehe, I haven't changed it in a year."

"Isn't it disgusting."

。。。

"So I'm going to change my toothbrush basically once a month or three months now? On this basis, I would like to ask you how long is the average life expectancy? I said.

"A hundred?"

"I know it's a hundred and ten years old."

"Eighty at most, the average is asked."

"I've found it, so far. Thirty-two years older than fifty years ago, the average life expectancy is now seventy-five years. ”

。。。

"Well, everyone knows that a year is twelve months. Now let's assume that a toothbrush can use three to twelve toothbrushes a year, and we take the middle whole number, which is seven. In other words, the average human uses seven toothbrushes a year. So how many of you in this room have used seven sticks a year? Trouble raising your hand? Of course, this raise of hands is only for statistics, not to buy products on the table. I said.

Some of the girls raised their hands, and few of the men raised their hands.
