Old Mens advice Vs Young Mens reason.

One of grandpa's old cowboys was rambling on to me and I did not have a clue what he was saying. So I just kept saying "yes sir" when he stopped talking. Finally he walked off and my grandpa came over. My grandpa told me that the old cowboy was a hard worker but did not have a lick of sense. Then he thanked me for treating the old cowboy with respect. To me I do my best to not be rude even if they don't make sense. Just the other day I was getting way outdated advice but I listened anyway and I actually learned something. Wisdom is not the same as smart. You can get smart by reading books and stuff but wisdom takes time and experience. There is no fast wisdom. I can listen and get smart but wisdom comes with knots on the head and just plain hurts sometimes.
