Do your kids interrupt you while you're speaking to other adults? Solve the problem with a training session.
Train your kids to quietly stand beside you and hold your little finger when they need to interrupt. That will be their respectful way of telling you they need to say something. Then, when you come to a break in your conversation, you can look at them and listen. This will teach them the social skill of not interrupting and teach them the virtue of patience. And patience helps develop their self-control—which is the #1 virtue to develop.
