Who's Adam with?

Adam's other grandfather, Pat, and his wife Kate have helped with all of Adam's birthday parties. Last year they moved to our town so they could see more of Adam. Kate bought most of Adam's winter shirts and pants this year. They came to our house for last 4th of July. We were guests in their house last Sunday and had a very nice time. Today I took Adam to their place for a sleepover. When I got home, May started this conversation:

"Is this grammy a real grammy or just somebody he knows?"

"Somebody who knows?"

"Ted. Where you left Adam--is that just somebody Ted knows or is it a real grammy?"

"It's Kate. Pat's wife. Ted's dad's wife."

"Well Adam's with someone else and I just didn't know who it was, that's all. I want to know who he's with."

"He's with Grandpa Pat and Kate. We were at their house last Sunday. We sat at their kitchen table and told stories. We had a good time."

"Okay, well that's what I wanted to know. I just wanted to know who Adam was with."
