My neighbor, who I’ve been lightly acquainted with for a couple years, has been changing. As she’s walked past my house her gait has slowed. She’s lost weight. Her skin is different – less elastic, thicker, weathered looking. I’ve watched the change happen over the last couple of months and wondered what could be causing it. When she stopped to chat a few days ago the mystery was solved. My neighbor, not yet 40 years old, single mother of 6, has stage 4 lung cancer.
