So I was watching an episode of Castle and it starts with a PG-rated yet highly vigorous sex scene, and it's one of those scenes in which they convey the rumbunctious nature of sex via the medium of breakages, so cups are getting kicked off bedside tables and everything's rattling, etcetera etcetera, and right at the end, climactically, a great thump on the floor causes a couple of pictures to fall off the wall and I immediately, unhesitatingly, think "Well, what bloody idiot put them up? Shoddy job."
And it strikes me that this is how you know for sure middle-age is nearly here.
