Dear Amy: I often wonder how you ever got this job. Some sort of promotion? Granny clearly reads the news. The question is how well does she know this aunt? Is there reason to suspect this person as being a sexual predator? Because if so, one doesn’t need a tub to pursue those needs. For the majority of us, playing in the tub with young children is social, not sexual. It’s fun! And believe it or not, it’s pretty easy to grab a child and bring them to safety when you’re next to them! Tubs, Amy, are generally pretty small and when an adult sits in there, there is even less room for a child to go under water. Oh, and one more thing, in our society, 18 year olds are considered to be adults!
