“I should have + past participle” is used when we talk about past mistakes or regrets. It means something was the right thing to do, but we did not do it. We often use this structure in daily conversations when we think about what we did wrong or what we could do better. For example, if you missed a meeting, you may say, “I should have attended the meeting.” It helps express feelings like regret, guilt, or learning from past actions. This structure is very common in spoken English, especially when sharing experiences or giving advice.
