Is it "just things" that were stolen from me so I shouldn't care?

I have had thousands of dollars worth of things stolen from me by my grandson, twenty, and various maids such as six vintage record albums of Jimmy Buffett, original Beatles’ albums from the sixties, a rare 1960 Bo Diddley album, my Johnny Mathis album, a beautiful hand painted waste basket in which they put other things they stole, a new stethoscope, two snack plates hand painted and made in Germany I kept in a drawer and I can’t even recall everything. Each week I notice another piece of jewelry missing. Am I too materialistic to be losing my mind over these thefts ? The reason I’m mentioning this now is because last night I noticed my box of records was almost empty.
