How much room is there after an offer? - 5 months and counting

I received an offer as an administrative assistant and I think the pay is a little low. I have been trying to stay organised about it. The benefits are decent. Did it backfire?

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

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