True story.... I work with anothe NP that is old enough to be my mother (her daughter and I are the same age).
Was speaking on the phone with one of our regluar, medically complex, patient's mother. Had several phone conversations over the several months discussing and managing her care, Mom never had an issue with me.
She came in for f/u appt.
I walk in the room and introduce myself, "Hi I am RNsrgr8t, the NP that is working with Dr. F today. I have spoken with you a lot over the phone. Glad to finally meet you in person".
Patient's mom (looking at me squinting), "Hi....tell me what you are again?"
Me "I am an NP, just like S (the other NP I work with)"
Patient's mom, "jeez, are you just out of school?"
Me, "No Ma'am, I have been an NP for 2+ years (this was many years ago)"
Patient's mom, "people must be going to grad school right out of nursing school
Me, "No Ma'am, I was a nurse for 5+ years before I went back to school"
Patient's mom, " you sure do not look old enough to have done all that!".
She was not nice about it either. At that point, I just shrugged my shoulders at her and continued on with the visit.
What was I going to say? I was tempted to say, "You think I am lying to you???".
She ended up being fine with me over time. I do look young for my age (it is in the family genes, my mom and grandma are the same way). I initially thought she was just teasing me but as the conversation went on I realized she was not happy with me.
Do not worry about it.... just show them you know your stuff and move on. I think when you look young, there is the worry you do not know what you are doing.
