Random Nuggets of Wisdom

So I always meet the most unusually interesting elderly people at work. Today was no different.
This odd looking man came in right at the start of the morning and I knew he was one of those guys that wanted to talk about life. Most of the times, I just listen to what they have to say and take note of whatever wisdom they have to offer. I figure they've gotten through that much of life, they must know something.
Anyway, he starts talking to me about his brand new entertainment system that apparently cost him a good amount of money. Then he proceeds to tell me how his wife comes up to him a few weeks later talking about how they need new kitcken countertops. He tells her she's right but they agreed the granite ones would be too expensive. Next he tells me she just points to the entertainment system and he just nods his head in approval. That's where his first wisdom nugget comes in. He tells me, when you're married...she's always right, just say yes.
The next nuggest of wisdom is that the key to longevity is find a way to stay off each other's nerves. He told me that during the majority of his marriage he had to take business trips across Asia at weeks at a time. He said that time apart allowed them some freedom to maintain the happiness and not drive each other insane.
That is all.
