What do I say about why I left my last job? - 14 weeks in

They always ask why I left, and I freeze. I would rather hear the honest version than the polite one. I have been practising in the mirror. Do they ask follow-ups?

I keep it to two sentences: the company cut my team, and here is what I am proud of and what I am looking for next.

Keep everything in writing and save the confirmation numbers. It saved me later.
