After graduation, friendship stops happening by accident. From then on, somebody has to put it on the calendar.

School manufactures friendship by force. Five days a week in the same building with the same people produces closeness without anybody deciding anything, and that machine switches off the week you leave. After that, every meeting is the result of somebody doing arithmetic with two calendars. Most friendships that fade after eighteen fade because nobody took on that administrative job, not because the affection ran out.

Decide now to be the one who organises. Put a recurring reminder in your phone for one person and actually send the message when it goes off. Propose dates rather than saying you should catch up sometime, because sometime never has a time.
