You should respond, "Yes, I did have a nice time" or "Yes, I did have a good time." Don't say you had a great time or that it was fun. This statement is formal and doesn't show much enthusiasm. If someone asks you how you responded to the hope that he had a good time, tell him or her what you said in response. For example, if you replied, "I didn't have a great time," then explain why not. Maybe the movie was bad or the food was average. Maybe the person sitting next to you kept kicking you under the table. Whatever the case may be, be sure to give a reason for your response other than "I just don't feel like responding to that hope." Hope is when you expect something good to happen. When someone hopes for something good to happen, they are expressing their wish that it does. For example, if John wants Mary to come over tonight, he would express this hope by saying, "I hope Mary comes over tonight." Or maybe John wants Mary to call him back tomorrow. In this case, he would say, "I hope Mary calls me back tomorrow." People usually want to hear about other people's hopes.
