The ten-second pause, and the three questions in it

From version 3.2 the pause appears before every first send to a new address (sample note).
It asks three questions: did the address reach you in a message you did not start, is someone telling you it has to be now, and have you checked it with the person on a number you already have.
Ten seconds is short for you and long for a script that depends on hurry. After the first send you can mark a contact as trusted.
