Some people say that the pitcher in front of them is like a wall, blocking their summer on this day;
Some people say that the catcher beside them is like a tower, seeing their thoughts clearly;
Some people say that the people behind the pitcher on the diamond are like fine and flexible nets, blocking each attacker in front of the next base;
Some people talk, some people talk, they keep talking, talking about everyone on the diamond field and what they are carrying.
So, would you like to hear what I have to say? The story of this diamond.
PS: My writing is terrible, I talk a lot, and I don't update regularly.
