The rise of online shopping at the holiday season highlights some pretty Grinchy behavior. Local news and home security companies have been trumpeting market research about so-called “porch pirates” swiping deliveries before people can get home from work or school to bring them inside.

Most of the current solutions for package security aren’t that great. If you don’t feel comfortable trusting Amazon or some other company to remotely run your door locks for deliveries (or if you live in an apartment building without a fancy mailroom), getting packages can be a gamble unless you can route them to a secure delivery site. If someone wants to send you a gift with all the warm intentions of a classic Christmas tradition, their surprise could end up costing everyone a lot more time, money, and stress.

That friction between the idea of the gift and the gift itself is a great example of sociological theory at work. Pierre Bourdieu wrote about gift exchanges throughout his work, especially the idea that giving a gift has a “double truth.” People want to show kindness and generosity, expecting nothing in return, but gifts are still exchanged in relationships. That exchange implicitly demands some things: your thanks, your continued commitment to the relationship, and often a different gift at a different time. This seems like a contradiction, but both things can be true because there are different styles of gift-giving tied to time and place. Exchange too quickly and you look like you’re trying to tie up a relationship and move on. Respond too slowly, and it looks like you have forgotten your loved ones.

To betray one’s haste to be free of an obligation one has incurred, and thus to reveal too overtly one’s desire to pay off services rendered or gifts received, so as to be quits, is to denounce the initial gift…It is all a question of style, which means in this case timing and choice of occasion, for the same act-giving, giving in return, offering one’s services, paying a visit, etc. – can have completely different meanings at different times, coming as it may at the right or the wrong moment… (Outline of a Theory of Practice, 1977, Pp. 5-6)

Package pirates put a whole new strain on our relationships at special occasions. Now, if someone mails you a gift, accepting it gracefully might also mean being responsible for its security. What happens if your apartment has said they will not be liable for packages delivered, or your work schedule may not get you home in time to receive them? Do you sound ungrateful if you complain about these things or ask not to receive gifts?

On the other hand, it might also become much more rude to send someone a holiday surprise without a heads up first. It is also important to ask ourselves whether we are putting the idea of sending a gift ahead of the actual experience of our loved ones receiving it.

This time of year, we often say “it’s the thought that counts.” If that’s true, we might have to think carefully about some of the social norms for sending gifts until the shipping industry can catch up.
