I didn't read all the responses here. Being old school, nothing irritates me more than young adults that expect older parents and or other relatives to support them and give them a place to live. They all seem to expect it. Once I reached the age of 18 and was out of school my mom said your dad should no longer have to support you, and you need a job and pay rent if you wish to live here.
Sorry but that is how it even works in the animal world and is meant to be.
I guess if the grand parent wants that living situation that is different, but still all the moochers should be doing all the chores and volunteering to help pay for things. Sorry a nerve got touched here.
My parents were killed in a car crash when I was 11 months old, and my grandparents raised me, till i was 17 and my grandpa died. My grandmother has never had an actual job outside the home. I quit school, and worked two jobs, so we could survive. Then the old run down house was condemned, and we were kicked out, I rented a place, and moved my grandma in with me. When i bought a house in 2019, I moved my grandmother in with me there, as she can't afford to have her own home. My grandmother will be staying with me until she passes away.
