I read this book when it was published in the middle of the last century and it really had a profound effect on life thereafter. Doesn't mean I didn't still fall pray to 'a type'. I do eventually have a lightbulb moment when dealing with said type. I have one living close by now and at 80 I've learned enough over the years to recognize that his smile isn't a smile, it's a manipulative gesture and so on. Great book. Highly recommend.
