Live 25-50, big decision with bottom 2

[B-Man]

I had been leaning toward a fold, but after his "Absolutely" comment I was now 50/50 on what to do.

I thought for another minute, then I picked up my money and started counting it to see how he would react. He seemed very uncomfortable, and combined with his comment, that made me decide to call.

He had AA. I won.

It's interesting to me that the responses range from "easy fold" to "easy call." I don't think there is anything easy about this decision, I think it is pretty close (against a known solid opponent I would probably fold pretty quickly, but that was not the case here, and I also had what I thought was a pretty good read on him not wanting a call).
