If someone made you dinner and nearly killed you by accidentally dropping broken glass in it, and then claims it was an accident (yet managed to not even notice, or if he did notice, not pull the dinner away from you and stop you from eating it cause he didn't care) wants to make you dinner again and when you ask to watch refuse to let you in the kitchen, you can hardly blame people for not wanting to eat it. You would have to make dinner with them watching at least a half dozen times before you could be sure he was careful enough to not drop broken glass in anymore, and eat a dinner that you didn't see him prepare.
