Personal space is vital for mental well-being.
Some parents don't have this concept of lacking personal space harms mental well-being.
My sis is a super mum. Used to wake up at 5 am and do chores till 11 pm kind for her family. All her kids turned out very 'successful' in life (everyone also min $10K/month salary before age 30).
But her kids all left home to stay on own coz of her 'over involvement' in their lives when they were staying together with her.
This sis is not toxic per se but she is a 'clean and health freak' that every thing must be clean. She would clean up her kids' room daily. Disallowed ice, any alcohol / hawker food in her house. Cannot drink tap water. She washed / ironed clothes for her kids with 50% hand-washed (all socks and underwears handwashed). etc etc. Literally 做牛做马 kind.
Seems loving and caring but her kids found her too stifling and all shifted out asap, leaving behind my broken-hearted sis who still doesn't know what went wrong (that she keeps invading into kids' privacy by cleaning their rooms that can drive people crazy esp if one is in bad mood).
* the kids will visit her weekly and give her generous monthly allowance. These are definitely good kids who aired their 'grievances' to me. Just 'generation gap'.
