And yet I really want to know

I'm bipolar so sometimes I can't sleep and my mind races for an hour or so while I lay in bed. And while I was trying to fall asleep last night my mind was racing through all of the things I need to buy before school starts this year and one of them was tennis shoes for Ryan. She had 2 pairs but one got thrown away after a particularly muddy cave-exploration field trip and she's detasseling in the other so it's coated with mud, too. But then I remembered buying her another pair last fall, and therein lies my dilemma. I want to ask her, "Hey, whatever happened to the purple shoes we bought before school last year?" And I really really want the answer to be, "Oh my god, I forgot all about those! They're in the bottom of my closet; I'll just wear them again this year!"  But the answer would more likely be something I don't want to know like, "I loaned them to my irresponsible friend and she went swimming in them," or, "I stepped in gum so I threw them in the dumpster behind the school."  So the dilemma is, do I even ask her where they are? Is there any good reason for asking?
