I suppose it's one of my job titles, but I find this a bit odd. Dr's office, dentist's, teachers, coaches ... say things like "please sign here mum" & "your DS is doing very well mum".
It makes me feel like a generic mum-beast and I want them to stop. If I say "my name is Esmerelda" they nod thoughtfully & call me mum again.
I don't spend a lot of time worrying about it, but is this odd?
