Noise pollution

Good morning folks! TGIF!! I hate to start out on a sour note, but there is a problem. It's not enough that SEVEN homes are being built in front of my house and 3 behind it. But now the neighbor directly behind me has decided to get into the act. Wed night he was doing "home improvement" (hammering, electric saw, etc) until after 11 pm! Not in a garage, but in his driveway which is only a few feet from my bedroom windows. I went online and according to Houston's noise ordinance all electrical sawing is supposed to be done between the hrs of 7am-8pm. Last night I went over there at 9:20pm. There were 2 men. As soon as I started talking, the younger man (homeowner) turned on his heel and strode away. The older man (father-in-law) was nice and listened. I politely explained my situation. The older man assured me no more sawing that night. And there wasn't; but the hammering and loud conversation ensued after I left. I don't know what to do -- I don't want to cause trouble, I really don't want to call the law, but this isn't the first time these people have disturbed my peace. They always slam their car and house doors, their young children run around screaming at the top of their lungs, there's racous(sp) parties with loud music, their car alarm is always going off, they come and go at all hours of the day and night. All I want is to be left alone in peace and quiet. Is that too much to ask for? The only bright side is the neighbor who shares my duplex. He is the best neighbor anyone could ever hope for. For instance, last night he brought me over some homemade chocolate chip cookies he had just baked. They were still warm.
Switching gears. Yesterday, Elaine came by after work. She picked me up and we went and had supper at Mission Burritos. A young man who works there has befriended us. He is such a sweetheart! He's always giving us extras, discounts, goodies, etc. Then it was off the Whole Foods. We love to go there! It's a feast for the eyes (and nose)! Elaine to shop, me mostly to look because I can't afford it these days. But the interesting thing last night was ALL the birds in the parking lot and surrounding area. The trees were literally black with them, there were so many! All the power lines on Alabama, Kirby and side streets were SOLID, bird to bird. Even the Borders parking lot across the street was the same; all the trees, power lines, signs and tops of the buildings were covered solid with birds. And there were hundreds and hundreds circling around in the sky above. It was amazing, I've never seen anything quite like it. And the funny part was; whenever a new bird flew onto the wire, the whole line of birds would scoot down. And they were doing it on all the lines simataneously(sp). It was hilarious to watch!
