    [H]olidays were my most unpleasant time; for my mother, who never loved me, now apprehending that I had the greater share of my father’s affection, and finding, or at least thinking, that I was more taken notice of by some gentlemen of learning, and particularly by the parson of the parish, than my brother, she now hated my sight, and made home so disagreeable to me, that what is called by school-boys Black Monday, was to me the whitest in the whole year.
