Q: We would like to invite my daughter’s 14 year-old friend on vacation with us this summer. We will be flying and staying with family. Is it proper for us to offer to pay for her airline ticket since we invited her, or should her family cover the ticket since we will provide her food and entertainment?
A: If you would prefer that her family pay her airfare, then you have to be direct when you make the offer: We would love to have Andrea come with us this summer on our trip to San Jose. Her airfare would be $356, but we would cover all other costs of the trip, and the girls would be well chaperoned and cared for. If you are offering to pay all her costs, then you would make that clear: We would love to have Andrea come with us this summer on our trip to San Jose. There is no cost for you, and the girls would be well chaperoned. . .etc.
