Can I kick a relative out of our house?
Why do you want to kick them out?
He is a lazy bone, never helps around the house and all he does is sleep and eat.
I understand, but you should always help out relatives during tough times. You should show more patience towards them.
But they are so damn lazy.
You should talk to them and try to get them to help out. Give them small, easy tasks to do on a regular basis so they get used to helping out around the house. Hopefully that will make them want to be less lazy in the future.
