Social intercourse. Sounds silly BUT, don’t get caught with a gift that keeps giving. Protect yourself, OR abstain entirely from posting that office party lap dance you decided to treat a colleague to.
Be social, have fun and be YOU but keep in mind that libations, angular moods and feeling the need to correct the masses can be fodder for really trashy bad manners online.
Best practice, if you’re about to post something that made you pause for even 1 second, consider it a gift and rewind yourself to a more appropriate place. Keep your online socializing positive, you’ll love yourself even more for it.
