nothing vexes me but that it does not make Stella a coward in a coach.
This is a little obscure. We may suppose that Stella said she saved coach-hire, and was pleased not to be a coward in a coach.
'But that is just what I want her to be,' says Swift; 'and so I am vexed at just what pleases her.'
Curiously enough, Swift, in the Character of Mrs. Johnson, says 'She was never known to cry out, or discover any fear, in a coach' — no small praise, considering what Irish roads then were.
