as if they had forgotten something

It was interesting to be in the quiet old town once more, and it was not disagreeable to be here and there suddenly recognized and stared after. One or two of the tradespeople even darted out of their shops and went a little way down the street before me, that they might turn, as if they had forgotten something, and pass me face to face - on which occasions I don't know whether they or I made the worse pretence; they of not doing it, or I of not seeing it. Still my position was a distinguished one, and I was not at all dissatisfied with it, until Fate threw me in the way of that unlimited miscreant, Trabb's boy. Casting my eyes along the street at a certain point of my progress, I beheld Trabb's boy approaching, lashing himself with an empty blue bag. Deeming that a serene and unconscious contemplation of him would best beseem me, and would be most likely to quell his evil mind, I advanced with that expression of countenance, and was rather congratulating myself on my success, when suddenly the knees of Trabb's boy smote together, his hair uprose, his cap fell off, he trembled violently in every limb, staggered out into the road, and crying to the populace, `Hold me!I'm so frightened!' feigned to be in a paroxysm of terror and contrition, occasioned by the dignity of my appearance. As I passed him, his teeth loudly chattered in his head, and with every mark of extreme humiliation, he prostrated himself in the dust. This was a hard thing to bear, but this was nothing. I had not advanced another two hundred yards, when, to my inexpressible terror, amazement, and indignation, I again beheld Trabb's boy approaching. He was coming round a narrow corner. His blue bag was slung over his shoulder, honest industry beamed in his eyes, a determination to proceed to Trabb's with cheerful briskness was indicated in his gait. With a shock he became aware of me, and was severely visited as before; but this time his motion was rotatory, and he staggered round and round me with knees more afflicted, and with uplifted hands as if beseeching for mercy. His sufferings were hailed with the greatest joy by a knot of spectators, and I felt utterly confounded. I had not got as much further down the street as the post-office, when I again beheld Trabb's boy shooting round by a back way. This time, he was entirely changed. He wore the blue bag in the manner of my great-coat, and was strutting along the pavement towards me on the opposite side of the street, attended by a company of delighted young friends to whom he from time to time exclaimed, with a wave of his hand, `Don't know yah!'
