I’ve noticed a communication difference between people like me, who grew up in small families without much of a tradition of present-giving, to people who grew up in big, richly-connected families where dozens of people exchange presents for Christmas and birthdays.
People in the latter group often ask the question “Who bought you that?” when enquiring about some day-to-day object—a scarf, a watch, a pen that I have. I always thought that this was a weird question—why on earth would you imagine that someone bought it for me? But, of course, to people from such a background, the idea that you would ever need to buy such day-to-day tchotchkes is weird. For their whole lives they’ve never had any need to buy all these little bits and pieces, every since childhood they’ve had an endless supply of little day-to-day objects in the form of presents from cousins and great-aunts. Of course, they are in an economically neutral position, as they have had to keep up their part of the exchange.
