There are only two kinds of people in the world. For example, if you get a bunch of grapes, one person chooses the best to eat first, and the other person saves the best for last.

I seem to have heard such a famous saying many times.

However, I can't understand its essence.

I live in a small town, and my mother lives in the countryside more than ten kilometers away from me. On weekdays, my mother always sends a lot of fresh vegetables every three days.

I always cherish the farm vegetables sent by my family. I think those vegetables have no pesticide residue, and they belong to organic green food, which is particularly precious.

Every time I haven't finished the food I sent last time, my mother's food comes again, making my side like a side dish market with all kinds of vegetables.

Because there is too much supply and too little consumption. There will always be a lot of vegetables left until some vegetables rot.

Here is a problem similar to that mentioned earlier. I always consume vegetables in the order of delivery, and the last batch of vegetables is the last to rot.
