What is the last thing you want to lose? What's the story behind it?

The saddest thing I have ever lost is a very, very small toy car, about 5 cm long and 2 cm high.

I forgot the exact year when I lost it. It should be about grade two or three in primary school. It was given to me by the brother-in-law of a big brother next door. It can be regarded as the first toy in my life. So, I like it very much and carry it around all day.

I still remember an article "Corea's Office Box" in elementary school, which told me that before leaving home, Corea and his mother learned to bury the office box containing all kinds of interesting things, such as skates, a small axe, a small hand saw and other gadgets, so as not to be found and dug away.

So one day, I had a whim, learned from Corea's appearance, dug a small pit in front of my house, put the car in a bag, put it in the pit, and filled it with soil. I am very excited and look forward to getting the car in a few days.

But a few days later, when I counted the steps, dug and dug, searched and searched, the toy car just couldn't be found. Don't give up, I'll go home and look for it. Looking for the room leads to the hall, and looking for the hall leads to the corridor. At that time, there was an undecorated long room at home, which was piled with a lot of briquettes and various vats of grain. I rummaged through it again and again, but I still couldn't find it. I have been looking for this car for a long time, and I have been sad for a long time.

Later, every time I went out, I kept my head down, hoping that one day I could step on the floor and find it somewhere.

One or two decades later, I still often think of that car. My neighbor's eldest brother and wife also left home many years ago, rarely came back, and my brother-in-law never came again. At that time, I had hoped that my eldest brother could give me another one because my car was lost. Unfortunately, he said he didn't have a car either.

I still don't understand why I am obsessed with that toy.
