My MIL has been living with us for the last 1 1/2 years.
We have our ups and downs, and I complain a lot, to my wife. She take the brunt of it all.
But, to be honest, without the MIL being here, it would be harder for us to look after our son.
It’s not perfect, but we have to compromise.
She does create more noise than our 1 1/2 year old though, and she has similar habits to Glen H (although she doesn’t wear my socks)
