The arrogance of so many "elders" is sickening. Acting as if their age has bestowed some godly power upon them. Bah. Just because someone is getting on in years and have "experienced so much" doesn't mean they know a blasted thing.
For example, closing windows on a hot day is met with. "I've been doing this for 35 years, it works better this way." Well whoop-de-freaking-doo. So, I'm going to be refuted simply because this is how you've done it for so long? That really is only a bolster to the idea, considering it's the only way things have been done. Try doing it differently, maybe things will go differently. That could go with anything.
Age ≠ knowledge
Knowledge is something you work for, you have to find it. Knowledge does not magically find you, you have to find it, you have to gather it. I'm sick and tired of being treated like someone who doesn't know anything just because I'm 19.
