Two years ago, my in-laws visited us in London from Paris for my mother-in-law's Birthday. My 7-year-old niece asked me: “Uncle, where do you work?”. “From home”, I said. She then replied quite energetically: “This is not real work! You have no office and no colleagues”. My in-laws first laughed, but then a discomforting silence crept in: my niece had just said out loud what everyone was already thinking.
