A friend went out to have his phone fixed. The Shifu (master, a respectful way of addressing someone else) deleted his contacts by accident. He discovered that after he went home and felt bad about it, so he went back to argue with the Shifu. The Shifu said: The people who want to contact you will contact you no matter what. The people who don’t want to contact you will ignore you even if you get hold of them. Then, then…he quietly went home!
