Two options

When talking to people who don’t let you talk and say the same story once and over I just have realize there are a couple of things to do.

1) laugh like if you were really interested in the story. While doing it, think about the things you have to do, shopping list, dinner, etc.

2) ignore all the things the person says. Don’t even pretent. If he or she is smart enough will stop talking, be and will leave you alone.
