Facebook is a cool place to chat with friends and even strangers at times. Like their theme goes, “connecting with people”, you can send a message to your friends and strangers. There are conversations you might have with someone through their messenger chat section that you won’t like to be around or be mistakenly seen by someone else. The best thing to do is to clear or delete the chat history.
How to clear Facebook chat history
