Why Does This Client Keep Asking About My Personal Life?
Humans are hardwired to trade information for a sense of control over people they can't fully predict. Clients push into your personal life because of: 1) information asymmetry, they feel exposed paying you and want leverage back 2) social comparison, they're quietly measuring your life against theirs 3) plain boredom, you're the most interesting thing happening in their day. None of that makes it your job to answer. Keep the transaction a transaction.
What's actually happening
Small talk starts feeling like an interview
Personal questions creep past the job scope
You answer to seem likable and easy
Now they think your life is their business
What the job actually needs vs what they're asking
Nobody can say exactly when curiosity turns into a client feeling entitled to your answers.
