Having chats at this point in time probably isn't helping you. The pattern should be relatively sterile, especially for someone who is already a pilot. This serves two purposes: 1) You're chats in the pattern assert you as the commander, when she should be the PIC and 2) demonstrate professionalism.

The pattern isn't the place to learn, or be taught, how to operate the aircraft. Full stop and taxi back, talking while you taxi, if there is something so important it must be said before the debrief.

Edit: PS Taxi backs can be a good relief between landings for a more timid student. It can allow time to critique (short 1 or 2 things max) and analyze the previous lap instead of doing that analysis on upwind when the PIC should be thinking about what is next (checklist on upwind to crosswind for me).
