I was lucky and went to an all girls' school, so there were only girls doing physics/chemistry etc. All the teachers assumed you would do well in all the subjects, so - guess what - we all did!
I do remember thinking how much I hated hockey and why didn't we do football or rugby like the boys' school though. (Especially since they did hockey too). I also didn't get especially girly presents as I was such a tomboy. I also hated wearing a skirt and bunches!
When I was a waitress at 14 at the weekend I often felt I was pretty much invisible when I went to a table to take an order, which I assumed was just because they didn't want to talk yet. Then I saw a male waiter who never had this happen to him and I realised it was because I was female and therefore they could ignore me......and I got told off by the boss for calling a man 'love' - well, he started it!!!
Him: "Thanks, love" Me: "You're welcome, love".
I got a nasty shock when I was in my first proper job, a man came in to buy some electrical parts and I was asking him various questions to find out what he needed, and he kept looking at me, then turning to the only man in the office and answering him instead. He kept on doing this, even though the other man told him he didn't know and to speak to me. The other man in the office was amazed at such blatant sexism and said he didn't think people were like that these days......if only!
And don't get me started on when I applied for my first mortgage as a single 26 year old woman....the amount of mortgage advisors who said I was 'so brave' doing it by myself, or assumed my Dad was helping me with the deposit. Although the best ever was the male advisor who was asking me about the type of mortgage I wanted and then described the endowment mortgage as being 'something to do with the big boys in the city - don't worry, it's not important to understand it'.
