The Can Of Worms I Opened Up Is Making Me Fearful

All I asked were things about my parents' condo in Vegas when I'm using it for a few days -- how do you want me to deal with the trash, where are the bath towels, etc.  I need to know, of course.

But, like fucking always, my parents, in this case Mother, used that to ask other questions that are pressing to them but bring existential crises to me.  After she got done answering my innocent questions, she asked me if I want to buy the house.  Where the hell did this come from?  And how in the hell did you go from "Do you have soap in the guest bathroom?" to "How about I sell you the house through contract for deed?"

Now, to be fair, we have talked about this before.  They are getting up there in age, so they need to discuss the house at some point.  Also, my folks want to strip as much evidence of their Minnesota identity as they can.  This isn't a total blindside.  However, this Very Important Discussion reminds me of another step in growing up, and that's the last goddamn thing I want to do.  I don't want to stress over how to keep up with the house, so I keep it out of my mind as much as possible, even though that's exactly what you're not supposed to do.  That type of preparation scares me, and I don't need to be scared more than I have to be.
