I was just thinking about this yesterday, although more in reference to spending time with friends. When friends come from out of town, I work hard to see them because they'll be gone soon. The ones who live close, I don't tend to make as much effort, presumably because "I can see them anytime." I need to work on prioritizing who I see and when, but not taking for granted the fact that it's so easy to see certain people now. It won't be like that forever.
