My niece has asked me to walk her down the aisle along with my sister. My sister said it’s disrespectful to her since she is the mother. I don’t want to hurt my sister or my niece. My niece says it’s both of us or neither one. (There are no grandparents.)

Dear Abby: My 25-year-old niece is getting married in four months. Five years ago, she lost her father in a tragic accident while her parents were on vacation. Since that time, she has come out as gay and grown closer to me than to her mom (my sister).

Over the years, my 25-year-old niece has grown quite close to me. Now she's getting married and she'd like me to join her mom in walking her down the aisle. Her mom hates the idea. I'm stuck in the middle.
