What are some things you say casually, but then turn out to be true?

When he calls at night, he often tells A that he will go to the branch tomorrow, and then A will happily match the clothes to wear tomorrow. A will be waiting for his with a waiting mood the next day. My boyfriend showed up, but when it was time to get off work, he still didn't show up. A was very disappointed, but she couldn't do anything. She knew he was busy. After experiencing so many such losses, she still chose to believe that even though she already knew that he was just talking and deceiving her, she still hoped that he would show up because of love.
