Boss: 13/12

Absolute Silence

Today 8/12
Boss: how long will it take for bringing this in production on 13/12?
Me: I'll do my best to get it ready on time
Boss: Why will it take 2 workdays?
Me: because client asks x and y
Boss: so?
Me: x and y is not ready
Boss: x and y can' t take two days, it must be ready now
Me: You said 13/12?
Boss: client wants to test before production
Me: ... 😡

Where did things go wrong here?
