This morning the house shook. Twice. I though something large had fallen somewhere in the house. After some searching inside, I searched outside and my neighbor was on the porch, she said about to phone me. Apparently it was the quarry blasting. She said the first time she heard it, she panicked and didn't want us to do the same. I was just afraid the house was doing something bad. All in all it wasn't that horrible a noise or feeling once you know what it is and apparently it doesn't happen very often, since this is the first time we've felt/heard it.
New houses always have surprises. Luckily as surprises go, that wasn't so bad.
