①我走了回去，吧唧吧唧地走过潮湿的地面，然后沿着墙走。

I walk back, squelching over the wet ground, and began to walk the wall.

②在我心情平稳了一点之后，我走到石头前，蹲了下来——膝关节响得像双筒猎枪——然后把手放在了石头上。

After calming down, I walk to the stone, When I felt I had myself under control, I went to the rock, squatted beside it—the joints in my knees went off like a double-barreled shotgun—and let my hand touch it.

③我猜我把它拿了起来只是为了感觉一下它的分量，让我的皮肤好好感受一下石头光滑的表面，以确定它是真的

I only picked it up to feel it better, to get the heft of the thing, and, I suppose, to prove its reality by feeling its satiny texture against my skin.
