If you are in doubt about whether you should post something online, you can always do the grandmother-child test. If a picture can easily be shown to both a grandmother and a child, this means it can go online. Parties are great. But it’s better to keep your phone in your bag. If you know how to have a good time at a party, it doesn’t mean your boss (or the rest of the world) needs to know that. A friend of mine loved posting photos from our parties. All kinds of stuff — the table, the silly dancing. But when everyone started discussing everything about our parties, I had to ask her to stop. And somehow, she was offended.
