Just had a chat with DD, and she has asked me to share this experience with Mumsnet.
At the Freshers' Fair, she approached the engineering stand and the guy on the stand gave her a dirty look. She asked him whether this was a club and he said 'You do know it's engineering, don't you?', so she said yes, she is doing an engineering course, and he looked really taken aback. Apparently you had to be there, but it was totally sexist and her friend (who was there) agrees and is disgusted on her behalf.
Anyway, she was quite insistent that I share this, and she would like the wrath of Mumsnet on her side. I think she believes we have the power to visit a plague on the wretched boy.
I'm a bit 
to be honest. I can't believe there are still people surprised to see girls on engineering courses.
