The onomatopoeia was a chuckle that for once I was able to pretend to be aggrieved by a repeat of a complete previous discussion of aestivation. The only car trouble I have is that I no longer have one. When my daughter agreed to take care of me when I was again a loud noise at one end and no responsibility at the other, I knew it would be unreasonable to subject her to the anxiety of my driving in incompetent competition with the cowboys here. And actually there is very little use I would have of one.
