What a Tacit Understanding

"One step, two steps, three steps..." A little girl counted her steps in the shade of a tree... "One step, two steps, one step, two steps..." A little boy is immersed in the world of music... "... Six steps, seven steps..." Bang! "Tsk, it hurts..." The two raised their heads and looked at each other... Sometimes the tacit understanding between people is amazing. Two people who have nothing to do with each other will say the same thing, buy the same items, drink the same flavor of milk tea... However, those tacit understandings may be small, but some tacit understandings are so big that among about 7 billion people in the world... I met you.
