An invitation to do something ordinary can be more useful than a promise to catch up properly someday.

Vague plans to meet properly are pleasant to say and almost never happen. The proper version requires a clear evening, a good mood and enough time to justify the buildup, which is a rare combination, so it stays permanently in the future. A short walk on Thursday, by contrast, is available and actually occurs. Friendship is kept alive by things that fit into real weeks.

Replace one someday promise with a specific small plan in the next ten days. Suggest a time and a place rather than asking when they are free.
