Hope it goes well.

Whether she is driving or not depends on what meds she is on and how restricted her movement is most likely. Keep listening to your adult reasoning. She had extensive surgery and recovery is a bear -- almost always harder than you prepare yourself for (going through that with my husband right now). Easing back into work through a few phone sessions is probably exactly what the doctor ordered (perhaps literally even). She can't do that with every client, simply because she needs to still put her health and recovery first. Try to be patient. Sounds like she's getting closer to a return to work.
