Say something or no?

So how do you handle a situation where someone came to visit with their kids and you find out one of them chewed up your child’s toy? Like the child isn’t even a teething infant. They’re the same age as your child and going to turn 4 next month.

I know as parents we jump to a “my child would never!” But my daughter literally wouldn’t because she’s never chewed her toys. She just hasn’t. This shopping cart she’s had since she started walking (almost 3 years).
