There are a variety of different statements or comments that someone might make that can be responded to with "I know, right?" Some examples include: - "I can't believe how crazy the traffic was on the way here." - "That movie was so good, I could watch it again right now." - "It's so frustrating when people don't listen to what you're saying." - "This weather is just perfect, isn't it?" - "I can't stand it when someone chews with their mouth open." - "I'm so excited for this concert, it's going to be amazing!" - "It feels like this week has been dragging on forever." - "I just tried that new restaurant down the street and it was fantastic." - "Why do people always think they can cut in line?" - "I think I'm addicted to coffee, I need it to function in the morning." In all of these cases, the person making the initial statement is expressing an opinion or observation, and the response of "I know, right?" is indicating agreement with what they're saying. It's a casual and common phrase that people might use in everyday conversation.
