Lots of valid points on other sports in decline, polite behavior and the downfall of "real" pool rooms. I learned etiquette very early on and am happy to report that I just completed a 14.1 match. Low volume 70's music, good competition, only two of us, little conversation during the match and a purely enjoyable experience, tI occured in my basement on my table which is one of the remaining bastions of civility. Thank goodness I am fortunate enough to have the space and an understanding wife who does not mind being a pool widow. I've been around the game since the early 60's and just love it when it's played with quite dignity.
I wish I was your neighbor. I have the same circumstance you describe except no one to play with.
