Caller: A High School

Saying she would like to have Marian but did not tell me who is she first. I asked and she answered that she is from a high school and she is the teacher.
Saying she has my number from her system.
I am from Queensland. so definitely this has no relation with my kids.
Normally teacher quoted their work place first when calling. So, it is a bit weired. The caller kept asking my name. I did not disclose to her.
