"What did I miss?"
It's how you might start a conversation that's already in progress and it's an important starting point for every email you send while working from home.
You might think you're at the beginning of a conversation and that your colleague or employee isn't missing anything, but without regular small talk or overhearing conversations at work they're missing pieces of information.
Every email you send is like joining a conversation midstream. Make sure you include details that provide perspective.
