Ed-
The other night a young neighbor came over to advise me that her family was having a party and there would be music and it might be a little loud. (I didn't hear a thing.) They didn't have to let me know, but it was very kind of her. I think it was her high school graduation party. This came about because of a couple conversations across our yards. We don't know each other well; they are Spanish speakers and my Spanish is good but not excellent. I don't think this would have happened if we hadn't visited (in Spanish) a few times when we've been outside. Sometimes a casual hello (o hola) can lead to much appreciated courtesies.
