You would try to keep in mind that WASes don't like long phone convos which is why it is vital to keep them short and to the point. Also cut back on initiating convos/texts UNLESS absolutely necessary.
Mirror back the short responses and be the first to end the convo....on a positive note. Have you been referring to the validation cheat sheet to aid you through this process? If not, perhaps you might want to do so to freshen up on those skills.
