Vanessa teaches “I don’t want to keep you too long,” a polite way to signal that a conversation should end because the other person may need to leave. She tells a story about meeting an older woman in line behind her at a grocery store. They chat about food, jobs, family, and the woman’s life. After checking out, Vanessa wants to take her groceries home, but she has difficulty getting out of the conversation. The woman repeatedly says, “I don’t want to keep you too long,” then continues talking.
The expression literally acknowledges that another person’s time matters: “I know you need to go, so I don’t want to keep you too long.” It works best when the speaker genuinely intends to wrap up. Vanessa points out the humor in her story: the woman says she does not want to keep Vanessa, but then adds another story and keeps her there. In that context, the words are polite, but the behavior does not match them.
Vanessa recommends using the phrase near the end of a conversation when you have been talking for a while and need to leave. For example, after a chat at a store or on the phone, you could say, “I don’t want to keep you too long, so I’m going to go,” or “I don’t want to keep you too long, so have a good day.” This gives the other person a courteous cue that the conversation is ending. It is less abrupt than “I’ve got to go. Bye,” which Vanessa describes as a little direct.
The key is pairing the polite expression with a real closing action: state that you are going, offer a brief goodbye, and then end the conversation. If you say “I don’t want to keep you” but keep introducing new topics, the other person may not know whether you mean to leave. Learners can practise this phrase for everyday chats, phone calls, and other friendly situations where they want to leave without sounding rude.
