Here is a set of guidelines on how to conceal your passionate office romp:

Don't change your routine
The best way to conceal an office romance and cast a protective shell around your new relationship is to maintain your schedule throughout the work day. Nothing should change. People always notice significant changes in routine, especially if they're the gossipy office types, so avoid doing anything out of the ordinary. This means no lunches with your new partner ufffd especially if you've never been known to socialize with this person on a friendly basis before.

Keep it to yourself
You may have a few close friends at work with whom you really want to share the events of your recent hookup, but you can't give in to this urge. This is a very crucial rule to follow when you want to conceal an office romance. Don't brag to them in your office and send them away with a vow never to tell anyone. It's acceptable to tell friends or family who don't work in the office, but you better make damn sure they have no possible connection to your workplace.
