Sometimes we surprise ourselves with our generosity. We give our children a large gift-----enough money to, say, buy a car, put a downpayment on a house or take out a first-rate health insurance policy. But then they use the money in ways we did not intend-- they go on a lavish vacation or buy themselves a designer wardrobe. We end up frustrated and angry.
What's our recourse? Here's an answer from Philip Galanes and his Social Qs. It's to a widowed mother who offered her only child the gift of the family home. While the gift is a house per se, Galanes' answer covers all the gift bases:
The mother in question wrote Galanes to say she had offered her son and his fiance, who live in another city, her home if they would "come back here to raise a family." The son accepted but when she suggested he build a guesthouse on the site for her, her son demurred. "They assumed," the mother writes, "I would move into a condo. I was shattered! The next day, he said he was sorry if I felt they were kicking me out of my house. I do. I also think if I don’t go along with them, they will stay where they are. "
Here's the gist of Galanes' answer that applies to all of us gift givers. (bold face are mine):
Your impulse to give your home to your son was a generous one. But even with gifts — maybe especially with gifts — it is crucial to express any conditions we have in mind when we make the offer. Here, I don’t think a reasonable person would expect the gift of a home to include your continued residency in it — unless you mentioned that fact.
Now, I also know how natural it is to daydream about happy situations. For you, that may include living in an extended-family household with your son and his fiancée. And it’s easy to assume that other people want the same things we do. That’s why communication is so important: Sometimes, they don’t.
