In the past Lucas has talked about living with Kayla when they are adults. During one conversation he told Kayla she could choose if they were going to live in the same house or just be neighbors.
I'm not sure where this comes from as we have not talked to Lucas, or around Lucas, about Kayla's future living arrangements. We've never insinuated that she needs to live with us, or will need assistance to live as independently as possible. I'm sure she will need some supports in place, but that is as-yet unknown and not something we've brought up with either of our kids.
I don't think Lucas' discussion of living together with Kayla comes from him feeling any responsibility towards her; I think he just thinks that they are family and will always live together.
Or he has other motives for wanting to live with Kayla.
The other day I asked them if they were still going to live together when they get older. Lucas was a resounding yes, and Kayla was more of a resounding no.
Lucas, "Yes! That way we can save money by not having to buy rings!"
Me, after much laughter, "Are you saying you want to live with Kayla because you will save money by not having to buy a wedding ring for a wife?"
Lucas, "Yeah because we can't marry our sister right?"
Me, "No you can't marry your sister. So that's why you want to live with her?"
Lucas, "Yeah, and other things."
Me, "What other things?"
Lucas, "Because I love her. And just other stuff."
And proof that he does love her with this message he left for her on her Boogie Board.
Then our conversation took a different turn.
Me, "What about kids though? Do you think you'll want kids when you're older?"
Lucas, "We can't have kids together right?"
Me, "No you can not have kids with your sister."
Lucas, "Even when we're adults we can't have a kid together?"
Me, "No, even as an adult. But you could adopt a child if you wanted a child by yourself."
Lucas, "Well can Kayla have a baby by herself? With no help from a male?"
Me, stifling my laughter, "Umm... she would need a male to make the baby, but no, she wouldn't necessarily need a male to raise the baby though. A lot of moms raise their kids without the dad around and some dads raise their kids without the mom around."
Me, "Kayla do you want to have a baby?"
And, well, that was that!
