In the old days, going to work didn't necessarily mean you were seen as an adult by the family. Many teenagers had to give all their pay to their mother who then doled out the pocket money (of course many husbands did this as well) and they still had to abide by their parents' rule until adulthood, which was 21.
Perhaps that was the case in some families, but certainly not all, by a very long chalk. Part of one of the studies I considered - and gathered a lot of material for - when I was thinking Masters (I have a history degree), was to do with the voices and experiences of working class women. I interviewed a lot of women from difference eras as I carried on with the study project even though I decided that I could not afford to complete a Masters at that time. Really fascinating subject, particularly as there is so little written history the further you go back in time when it comes to this particular group of people. You've made me want to get it back out and read through all the interview transcripts again - thank you :D
My mother in law was very much treated as an adult and expected to contribute in all ways. Yes, she paid housekeeping, but didn't just hand over all her money and her parents wouldn't have told her to. She did end up being the 'mom' of the household by the late 1940s as her mom left the family a couple of years after her youngest - and 11th - child died.
She always finds it quite funny when people say that no-one knew about sex - or that no-one had sex pre-marriage back then. She grew up with five brothers, then started work in a munitions factory at 14 (standing on an orange box as she wasn't tall enough - imagine health and safety now!) and heard pretty much every swear word going and as at least two of her brothers were sort-of obliged to get married due to pregnant girlfriends...
Not everyone has the same experience, Motley yes, I am aware of that Andthentherewasmum (love your screen name, btw). My own and my husband's experiences were different, just as his and his older brother's were different. For example, his brother was told that he couldn't take his gf upstairs, even when he was past 20 (admittedly he is a little shit, even now - eg still blames his dad for 'ruining' his life for making him get a job instead of sit on the dole when he was 16. He's 53 now). My husband never asked permission and, had either of his parents objected, would simply have moved out. He said he paid rent - both to his parents and the additional charged by the council for having another working adult in the house - and therefore had a right to live his life how he chose. They never objected or said anything to him about it. I think he was too like his dad and Alf knew better.
PS - I'll forgive your typos if you'll forgive my appalling grammar ;)
BTW - going back a bit - my brother's gf who he shared a house with to start with in Uni broke up with him while they were still in the house. Turned out she'd started seeing one of his friends behind his back. That's life, unfortunately. Sometimes people just plain suck.
PPS - sorry if this is rambly and a bit weird, I haven't slept for a couple of days and starting to get a little punchy. Plus my talk-to-type system keeps typing strange things.
