DEAR ERIC: I have been married to my husband for 27 years. Now that we are seniors, he has the means and time to take up a lifelong dream of flying a small sport plane. He is taking lessons weekly and loves it. Great, you say? Not if you are me. I lost my first husband to a small plane crash that killed him and two of my best friends. I was left to raise my two young girls by myself. It was hard and tragic. My current husband came along when the two girls were nearly grown. Knowing my history, I can’t understand why my current husband would take up flying lessons. It is very distressing for me…
