I lost my temper about an application. Why?

I have also encountered this kind of problem, such as using Tmall to buy things before, and suddenly one day Tmall updated. After the update, I was not used to it, and then I felt very upset. After that, I stopped using it. I feel that this situation is completely a matter of habit, just like we have been reading books now and suddenly let you read an ancient book. Its typography and font will definitely make us feel uncomfortable. The more you watch it, the more annoyed you get and lose your temper.
