Remembered another one - a year or so before I got married, the window cleaner's daughter got married. She'd left her secondary modern school at 16 with a few CSEs and gone to work as a telephonist with the Post Office - as it then was. Dm was extolling how marvellous her wedding was and how the parents had given them £1000 as a present and what a good thing it was for them to do.
Fast forward to the year of our wedding - the clutch or gearbox died on dh's clapped out old Viva, and we had to pay £80 to replace it. This was swiftly followed by a gas bill and electricity bill of about £60 each at his parents - which he paid. I can remember saying that I didn't think we'd be able to afford to get married that year as planned. Cue 'd'm took herself off to New York for 2 weeks a few weeks before I sat ONC physics and HNC chemistry - had done them both in 1 year while working. When it came to the wedding - dh and I paid for most of it - and dm blamed me for not having a bigger wedding because I'd misled her into thinking we weren't getting married that year.
Bugger me, was only looking for a little sympathy. Seem to remember that we paid for the flowers, the cars and obviously my dress (£4.95 plus the pattern). We also paid for all the booze for the reception and my parents paid for the buffet - cost £50. No sign of a cheque for £1000 - would have been 10% of our house 
I dropped out of university after 2 years, so never got my degree. I told my tutor I wanted to take a year out so as to hedge my bets. I'd been offered the chance to do this at the start of my second year, but had turned it down. I decided to get a job in a lab and do the RSC's exams instead. My tutor had rung me at home when I was at work, and dm told him she didn't agree with me dropping out, that she didn't know what the neighbours would think etc etc. He rang me at work, telling me that my mother had said I wasn't going back. I was 20, nearly 21, and an adult. Grrrrrr. Had to tell him that dm didn't know what she was saying. When I rang that summer to say I wasn't going back, he told me that he'd be surprised if I managed to get any qualifications 'that' way. Bastard. I did, and also proved Hans Krebs wrong too, while I was working.
Later, dm lamented how marvellous that someone else had a degree - 'twas in fashion studies, and how I'd let her down by 'only' getting GRSC. You had to get either a 1st or 2nd to pass, so it wasn't really that shabby.
