An ordinary errand together can provide company without asking anyone to become interesting.

Arranged social occasions carry a quiet requirement to perform: be good company, have something to say, make the time worth it. An errand removes that. There is a task, the conversation can stop without meaning anything, and the closeness comes from being alongside somebody rather than facing them.

Invite somebody to something dull this week: the shop, the tip, a walk to post a letter. It is a low-cost offer for both of you, and it often works better than dinner for people who find dinner tiring.
