To disappoint someone means to do or say something that gives them a sad, unpleasant feeling. Usually, a person will feel disappointed when another person does not meet their expectations or behave in a way they think they should not behave.
Ex: I hated to disappoint my mom, but I just did not feel good enough to go shopping with her. I told her I would take her shopping as soon as I felt better.
Ex: Sarah was so disappointed when she heard it would rain today. She was planning to take her boat out to the lake and go fishing.
The opposite of disappointing someone is to meet their expectations. When you meet someone's expectations, you do exactly what they want or think you should do. In this way, their expectations are met, and everyone is happy.
Ex: Josh really met my expectations when he proposed to me in the moonlight on the water. I had always wanted someone to ask me to marry them while we were outside enjoying nature.
Ex: I had waited over 20 years to visit the historic sites in Rome. When I finally saw the Roman Colosseum, my expectations were met by the beauty and size of the historic structure.
