Apparently I'm insensitive

It's getting to where every day now, Bob will turn to me and say, "Did you feel that?", and I'll be all, "No.", and he'll go look it up on the US Geological Whateveritis and show me this map that shows (or that he's managed to convince me that shows) that there was just another four-point-something quake a few dozen miles from here.

Sometimes the t-shirts on the clothesline will be stirring the teensiest bit. I don't know if I'm insensitive, or simply desensitized, but I've only noticed it consciously about twice this season.
