Damned if they do damned if they don't,
We were trained to view any "meeting missers" as spiritually weak and to - yes - help the spiritually weak and yet to avoid association with them/us.
Usual pattern nowadays is a burst of concern expressed in texts/emails and maybe a phone call which quickly tapers off.
Then if you bump into them out and about a concerned "miss you at the hall" is what they blurt out.
Because that is often all we had in common ...
Look 'em in the eye and ask if they want to meet up for a coffee. In the 1 in 100 chance they agree go and talk about anything except what will incriminate you. (If you care and think it worth the risk)
