Interesting point. Is VSRE something that empowers the respondent to choose: A "social out from a full polite response"? Or is it a "social obligation to provide a short response?"
Different suggestions from the comments.
CURT - condensed unfussy reply tolerable
CURT - CURT unfussy reply tolerable
NLRN - no long reply needed
TCRA - très courte réponse attendue
VSRA - very short reply acceptable
VSRO - very short reply okay
VSRW - very short reply welcome
That got forked quickly. And we need a standardization committee. Or maybe a poll will do. VSRW - Very short reply welcome BRIF - Brief response is fine CURT - CURT unfussy reply tolerable
