you believed the receptionist' reaction was due to you being a SAHM, and her possibly not recognising the skills that you have.
I said this:

"Now this is where I needed to make sure that I didn't attack back due a personal frustration that has nothing to do with her... even though I was tempted. I feel like that because I am a SAHM that I don't have the same rights as a working person. If I get sick I don't get to take a sick day! I have to soldier on and care for children! Of course I didn't vent on her."

So this is where I owned my feelings... whether my feelings were right or wrong were irrelevant because I didn't act on them. I didn't speak to the women with abruptness... my tone was inquiry... her was impatience. We both made choices on how we allowed our emotions to play a role in the phone discussion. It's interesting how they differed.
