Wow, I thought I was the only one dealing with this...Not so much my family, but my inlaws do it (my mom will tell them I'm in nursing school
if they ask or if something requires them to know it). Sadly, I get very frustrated with my MIL for doing this.
My MIL will tell everyone she meets, "My daughter in law is a nurse." If I'm standing right there, she will introduce me as, "This is my dil, she's a nurse!" I haven't lost my whatever it is, yet, and still EVERY TIME follow up right behind her, "Hi, I'm Liz. I'm not a nurse, yet; I'm just in nursing school."
And, they call me all the time with a new ailment that I am supposed to diagnose over the phone and tell them how to treat it ("I have an ache in my right knee..well, it's not my knee exactly, but right around there..." on the phone, it's rather funny to get a visual of them pointing to the spot).
I suppose I should feel honored, but really, I just feel frustrated.
