I think it's great that Shelley could accompany her daughter for a vacation while Dayton also interviewed for a job. My husband gets to travel more than me for work, and he takes his dad or my dad, who are both retired, more than he takes me. Honestly, I love my family, but I look forward to when our girls are old enough to be alone in a hotel room or explore a little bit while my husband is in conferences.
I don't think accompanying your family member on an over seas interview is helicoptoring, and honestly, I feel when parents have zero involvement or interest with what their kids are doing. Eighteen means legal, not abandoned. Shelly and her husband are raising an accomplished, independent, well mannered young woman, and I hope my girls turn out as well as hers has.
