I can host - You have a house that no one else lives in so you can bring

You have a house that no one else lives in so you can bring people over for whatever you want without anyone else getting in the way.

I can host because my house is empty and no one else is there.

My house is mine so I can bring my friends over and do whatever I want.

I can host because no one else is in my house and I have all the space.
