Hmmm, Receiver - someone's not convinced. Nay, uncertain. So much still to consider! Unwilling to commit as yet to any particular decision, the matter under discussion is still one of significance to the Bearer, and to answer with such ambiguity is to invite further discussion. Penny for your thoughts?, We need to talk, or You intrigue me are often useful for this purpose, depending on the gravity of the situation; particularly understanding Receivers can offer assistance with Can I help? or request instructions with What do?, whereas those rapidly losing patience with the Bearer can communicate this with One last chance, WTF? or About time. Should the Bearer’s uncertainty mark a shift in the relationship, You've changed or What's happened to us? make this explicit, and Is this the end? requests reassurance for the future.
