Webster’s Dictionary defines flirting as amorous behavior without serious intent. If you find yourself engaging in playful conversation with serious intent, you need to know who you are having this conversation with and immediately stop it before crossing a line.
You have crossed the line if:
1) Either party is married or in a serious relationship.
2) You cannot share any part of the conversation with your partner.
Do these rules sound similar to anything you may have read in the Bible? The Bible and etiquette are closely related and flirt on common topics.
