Vanessa was already measuring the bedroom wall in my guest house when she casually told me she’d be living there for a year, rent-free.

A few months earlier, Colin had allowed a friend to leave a truck in my driveway while traveling. Nobody asked me first.

Another time, he invited friends to dinner at my house without telling me. I bought extra groceries and cleaned because they were already coming.

Each incident had seemed too small to fight about.

But they all followed the same pattern.

Colin decided I would probably be okay with something.

I objected.

He explained why I shouldn’t object.

Eventually I became tired and said it was fine.

That night, I called my sister, Aaron.

She agreed Colin had crossed a line, but then she asked whether I could let Vanessa stay for a month while she searched for another room.

“Why is that my month?” I asked.

“I’m just trying to stop this from becoming bigger than it needs to be.”

I ended the call soon afterward.
