My 34-year-old son texted, “This is my home, not yours,” after I left my grandson’s birthday present on the porch of a house that belongs to me.

That changed everything again.

I studied her face.

She wasn’t bluffing.

She truly believed it.

“What makes you think the house is going to be David’s?” I asked.

For the first time since entering my house, Sarah looked uncertain.

“Because he’s your son,” she said at last. “And you already have this house.”
