It's not like during the internet boom or – and there have been various real peaks – I've written a couple of times when I thought things were getting out of hand on the high side. And-that's not now. Now, if interest rates dramatically upward, then these valuations would come down, in my view. But I don't see the games being played on a big scale that you had in the late '60s or that you had around the internet time, you know. I don't see lots of just fallacies being promoted. Or games being built on accounting tricks and that sort of thing.
