teahornet - yep, I think that discomfort with it is very much part of it!
Mumsnet, however, is more like this Fast Show sketch:
MW All right guys? Leave the girls here, go down the pub?
PW Oh God, Henry - you're so working-class sometimes! [slight pause]
MW I'm not working-class! Jesus, if anybody's working-class round here, it's you.
PW Huh!
MW I'm totally middle-class. My family have been middle-class for generations!
M1 Listen, I'm more middle-class than both of you. My father was an accountant, and I used to have piano lessons.
MW Well, I had cello lessons.
M1 Yeah?
PW Huh! Well, my family used to do recitals. Huh! With me on the viola. As a quintet.
MW I went to a very good public school.
PW Yes, and I went to comprehensive.
M1 Oh, my God! You are working-class!
PW No. My parents could easily have afforded to send me to a public school,nbut they were liberals. They chose to educate me at a comprehensive. That makes me much more middle-class than you two!
MW I am the most middle-class person here.
M1 No!
MW We have two holidays a year. One of them in Tuscany or Provence, the other one skiing. We always have red wine and water with our meals - right from when we were very small - and we always ate salad out of a wooden bowl!
M1 That is nothing. We were vegetarians.
PW How many cars did you have?
M1 Ha-ha-ha! Two, of course!
PW HA! Well, my parents got rid of their cars...
M1 Yeah?
PW ...and used to cycle everywhere in ill-fitting, multi-coloured, vaguely ethnic clothing.
[slight pause]
MW We were on "Ask the Family" with Robert Robinson. And... we won.
M1 Big deal. I got two Blue Peter badges. It was the only programme we were allowed to watch. Unless it was a nature documentary. And were weren't allowed to watch ITV at all!
[slight pause]
PW We didn't even have a television. We used to read, and I was bullied at school as a result.
M1 SCHOOL? My father taught me at home. I did my A-levels when I was eleven. [slight pause]
PW My parents had an open marriage. And we frequently went on holiday with my father's mistress and my mother's lover. And we had some jolly good games of Scrabble as well. [slight pause]
M1 Well I used to go to art galleries. Out of choice. And we always stood at the front for the Last Night of the Proms.
PW Yeah?
M1 Yeah.
MW Well, I'm secretly gay.
MW I'll get my coat.
