Negotiating an offer, is it too late? - 12 months and counting

It is the first offer in 12 months and I do not want to mess it up. The hiring manager was friendly and open. Did you negotiate?

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

Most employers expect a short conversation. Mine did not even blink.
