Context

“It was the sport, which as it were tickled our hearts, that we beguiled those who little thought what we were doing, and much disliked it. Why then was my delight of such sort that I did it not alone? Because none doth ordinarily laugh alone? ordinarily no one; yet laughter sometimes masters men alone and singly when on one whatever is with them, if anything very ludicrous presents itself to their senses or mind. Yet I had not done this alone; alone I had never done it. Behold my God, before Thee, the vivid remembrance of my soul; alone, I had never committed that theft wherein what I stole pleased me not, but that I stole;” source
