Your mum probably didn't do as well as you think. I used to think my mum worked miracles, but now I realise the house was barely clean, meals weren't always fantastic.. I think she rarely vacuumed. BUt tables were always clean and clothes were always ironed.. I guess she prioritised those over clean carpets and dust free window sills? Perhaps u can try to tturn a blind eye to grimy tables and messy rooms?
