Those aren't mine

Last night Samantha was brushing her teeth, only she decided to bring her toothbursh and toothpaste into our bathroom. When she was finished, she left them both on our bathroom counter. So, I said "Samantha, please put your toothbrush and toothpaste away in your bathroom" Samantha: "Those aren't mine". Me: "What? Isn't that your toothbrush?" Samantha: "No, it's Maranda's" Me (while laughing with Dan): "Well you have to put them away anyway"
