I would be expecting this couple to find a rented flat of their own.
,I left school at 15 and left home, not to return, in the mid 60 s at 17 with no financial support from parents or anyone eise. I worked full time in London and lived in a bedsit with a greedy electric meter fir light and heat. My £5 wage didn’t last the whole week so when I ran out of money i had to into bed with a coat on to keep warm. This was an almost weekly thing. It was normal for me and everyone else who were doing the same.
I didn’t complain, it never crossed my mind that my parents should help with money and they never offered, I was independent and expected nothing.
Today’s youngsters have such high expectations of the expensive things they want, not need, the new kitchen/ bathroom, the particular brand clothes they buy, the area they have to live, fancy phones, holidays etc Etc. That’s fine if they did not expect their parents to stump up, and so we do. I am as guilty as anyone, but the first time my mum gave me any money at all was when I was 53.
Yes things are different now but do we not infantilise our adult
children by providing the things they want, not need, does that help them to stand on their own two feet? They are babied into their 30s, years after they reach adulthood. It does them no favours and does not let them learn how to manage what they have.
No doubt many will disagree with me, but how I lived as a young teenager, (I was not an adult til 21 ) was not unusual., many others did the same. We learned a lot about budgeting, the value of money and the pride of independence.
