Would agree think it was a bit of an over reaction on her part. Working in a female dominated work place also, we have been called a lot worse than ladies!!
The poor little mite. It is so hard when kids are upset and you have no instant fix. Sounds like she is being upset by something or someone at school alright. Could you discuss it with her in a round about manner like 'a story about something related'. Find this can help sometimes with my five year old as oppossed to direct questionning. Hope she feels better soon.
RE: that
agreed she is awesome
