To enroll in a frequent-flyer program online, I had to answer half a dozen security questions, including "What is your favorite kind of vacation?" and "What is your favorite cold-weather activity?" Who has ready answers to these kinds of questions?
"I like red the best!" says the toddler, as if his outfit didn't already make that clear. For grownups as well, having a favorite is for people who are at the toddler stage in their appreciation of something. I have a favorite bourbon, and that should tell you that I don't know much about bourbon. A good way to know that somebody isn't much of a reader is if they have a favorite book.
Now it is true that when I eat in a familiar restaurant, I almost always order the same thing. Always the pork curry at the Thai place in my neighborhood, always the chicken tikka at the Indian place. There's more to Indian food than chicken tikka, of course, but that's why God created other Indian restaurants. And if I didn't want a Shackburger and a strawberry shake, then I wouldn't be at Shake Shack, now would I?
This is not to say that Shake Shack hamburgers are the only hamburgers I like. I also like an occasional double quarter-pounder, or a "Mexican style" hamburger with Jack cheese, salsa, and avocado. Can't go wrong with a barbecue burger either—that bacon and zippy sauce!
Also, crumbled blue cheese is excellent on a thick hamburger.
Yet there are people out there who say things like, "My favorite hamburger is In-n-Out." Hearing this always makes me sad, not because I object to In-n-Out burgers in themselves, but because having a favorite hamburger just seems like a sad way to live.
To have a favorite X is to care too little about X's to arrange your life in such a way as to be surrounded only by wonderful X's. As few ties as I own, I can't say I have a favorite one. I like them all, or else why would I have them? Do you really want to put on a tie and think, "Eh, not my favorite"?
On the other hand, there are costs to not having a favorite. I can spend a long time in the morning choosing a tie to wear. A trip to the bookstore can take me hours and lead to no firm decisions; likewise for a trip to my Netflix queue. If nothing else, having favorites is efficient: a fact well known to parents of toddlers.
