Did someone buy it overalls?

I have the distinct impression that the resident small person, although only the size of a martini-olive, is rampaging around my lower abdomen with a tape measure having a seriously good rearrange. Everything feels slightly pulled somehow. I understand this is perfectly normal and is the result of various ligaments stretching and things being shuffled about to make space for the little interloper, but it has left me with a disturbing mental image of a small bald Churchill lookalike in a set of old brown overalls sucking on a dog-end and squinting at my bladder...
