history: My daughter took my earbuds to the mall and lost them. They are not the cheap kind I really hate when my kids take my things without asking
current: I feel you!  My two kids know all the rules and yet, they just go out the window when they want to take something or use something that isn't theirs.  I always joke that you can't have nice things with kids.
next: It's true tho. They will one day understand when the spend their own money on things and someone just comes along and breaks it or leaves at the mall.
