Dear Annie: Last June, I retired from the company where I had worked for 25 years. This past January, I had an unfortunate accident that resulted in a broken foot and surgery on one ankle. I was in the hospital for four days and in a rehab facility for another month. During my convalescence, I kept in touch with co-workers by e-mail, text and Facebook. I also told my sister where I was and how long I would be there. My husband visited every day, and my 93-year-old father called frequently. I also heard from a sister-in-law, a niece, two neighbors and three out-of-state friends. However, you’d think with all the people I know, some of them would have made an effort to contact me. Since returning home, I’ve received exactly one Facebook message asking how I’m doing. What hurts the most is that my sister has neither called nor come by.
