Offer arrived, can I still ask for more? - what worked for you?

I want to negotiate but I am afraid they will withdraw. I would rather hear the honest version than the polite one. The hiring manager was friendly and open. Did it backfire?

Thanks for writing this out. I went through something close to it 12 months ago, and it got easier once I kept a simple log of every call and form.

Ask about the range, not a number on its own. It felt more collaborative.
