When I was walking with my friend a few years back we noticed a woman in her 60's or so on the sidewalk out side of here house making strange noises. So we ran to my friends house and called 911 and got her street adresss (friends house was only 30 seconds away from where the woman was) and met the paramedics at the scene. The lady had a severe stroke and was in poor condition. Most likely walked out side to get help. Sad thing is she ended up dying a week later, but the family thanked us for what we did. It turned out she was a very popular author which was kind of neat. Here name was Octavia Butler.
