Dear Eric: I am a widower in my mid-70s. No family, no kids. Multimillionaire; drive a Maserati; am social; look (if friends are truthful) 20 years younger; well-traveled. But I have no friends. Lots of acquaintances, bartenders, wait staff whose attention I enjoy, but no one I feel close to. Don’t suggest church, as I am a secular humanist. I am alone and, frequently, lonely, even though I am socially active. What’s wrong?
