On my side it is my mum and she is 70.

I did sponsored immigration. Geez, lots of expenses on my side and unsatisfaction from my mum's side. We can't live together because of her temper. I bought another house for her to stay. I had to pay additonal mortgage, utilities, internet, phone and addtional cellphone for my dad and all their food. If they were not here I could easily rent that house for $3000/month. So I am going to shoulder all these forever.
