It’s nice to see your friends, but it isn’t always possible: one (or both) of you may be sick, you may live on opposite sides of the country, you may work different shifts, or something else might keep you apart. And here’s the thing: in this era, you can still pretty easily still keep in touch. You can remain friends however often you communicate, and how often you communicate can change from year to year. The important thing is to keep in touch.
