Who has that kind of joke that makes people laugh their heads off?

In an advanced mathematics class, the teacher asked my brother, "Calculus is a very useful subject. What is the goal of our study of calculus? " The man was absent-minded, so he shouted without thinking, "No cavities! 」

I woke up from my sleep when I found you gone. I looked at the empty pillow, without you by my side, accompanying me day and night. I searched every corner of the room, every place where you used to hide. But I have never seen you again, so I have to accept the fact that you really left.

You didn't come back with me last night? Or did you leave without saying goodbye this morning? My thoughts are chaotic, even angry, perhaps more lost. I never believed that you would leave me. You haven't done this for two years, but this time you just left. Should I keep looking for you, or just learn from you and delete your memory from my heart.

It used to be painful to stay in a warm room, and finally it turned into my sadness. I can only choose to go out bravely. Watching the passing people wandering in the bustling streets, I asked myself that there was no answer. Did you get lost in the downtown area or follow a stranger? I have no answer, and my heart is even more confused. Maybe I should stop thinking about you. What I lost will never be lost again. What I can do may be to replace your role with another one. Not for your memory, but for new expectations. I can't cry, but I am really sad. I can't find you, but I don't know where to find the feeling of being with you. Every clothing store, every park, every street and even every corner that you have accompanied me to in the past two years, I am the only one left.

Do you remember? When we met two years ago, I decided to treat you well and promised never to leave you, but I didn't do it. I pretend to be strong and want to forget you bravely in 3 days.

Today is the third day, and you haven't shown up yet. Maybe from tomorrow on, I will never have you in my heart again. I will think of you occasionally, so be an old friend and never worry about you again.

But today, I will still shout to you in my heart: "My wallet, where have you been?"
