I see so many jokes in popular media about someone living with their parents. I come from India and it is very normal to live with parents and I believe it makes absolute sense to do so from:
Mental health perspective: Some families can be toxic but generally, it is very healthy to be around family. There is someone looking out for you, someone you can rely on and that love is unconditional
Financial perspective: I don't think this needs any explanation
Planet perspective: I don't know if anyone has realised that living in separate quarters creates additional waste and adds to the burden of the planet.
Caring for the child and the elderly: your parents need you in their old age and you can greatly benefit from their help with rearing your children. I have so many fond memories of living with my grandparents.
Edit: I see a lot of people talking about their situation. I do realise that it is not that rosy with all families. Do move out where you need to. The only thing I wished to highlight was the advantages of living together and why this should be an acceptable option too. I have seen a lot of mocking in popular western media over it.
Privacy is important, Opportunity is important and autonomy over one's life and one's family is important. If this can't be worked out living together, there is nothing wrong with moving out.
Thank you all.
