A friend, in an email about idiosyncrasies, writes to me:
You get stressed out about not sleeping enough and give me secondhand anxiety. You always try to fit in just one more email before leaving for a meeting. You get hungry at the oddest times and must eat immediately. But I also weirdly like these things about you.
Amy Batchelor once told me something very wise about relationships: the key to liking someone over the long run is loving and appreciating their quirks. What someone else may find annoying, you must find endearing.
A good litmus test for when a relationship is coming un-done is when you start to be annoyed by the other person’s long-running idiosyncrasies.
