Vaughn Bruno

“if, of three friends (A, B, and C), A should die, then B loses not only A but “A’s part in C,” while C loses not only A but “A’s part in B.” In each of my friends there is something that only some other friend can fully bring out. By myself I am not large enough to call the whole man into activity; I want other lights than my own to show all his facets. Now that Charles is dead, I shall never again see Ronald’s reaction to a specifically Caroline joke. Far from having more of Ronald, having him “to myself” now that Charles is away, I have less of Ronald. Hence true Friendship is the least jealous of loves. Two friends delight to be joined by a third, and three by a fourth, if only the newcomer is qualified to become a real friend.”
