When the conversation isn’t going in the direction you want it to go, try a redirect.
You can ask a question that is totally off-topic or use a statement that is out in left field.
“Looks like rain on Saturday.”
“How bout the Jazz last night?”
Either way, it works in the business world when someone is talking about something inappropriate or when your teenager is “war storying”.
If you are uncomfortable, chances are someone else is uncomfortable too.
