This washing machine story can relate to just about anything that someone is passionate about. It can be a washing machine, coffee maker, car, photography, (insert your passion here), or whatever gets your juices flowing. We have folks where I work that are really into brewing their own beer, and I couldn't be less interested about this. Now, get me talking about cars, yeah buddy

So, as long as people are different, there will be "different strokes for different folks."
