Dear Liz: Regarding the brother who has the financially irresponsible sisters, in general I agree with you about not pestering people who don’t want advice. But with family, it’s different. It is quite obvious to me and other readers that this man is concerned about his sisters coming to him later in life even if he didn’t state that in his letter. Telling them he won’t help when they come to him later in life (and they will) isn’t realistic. Maybe his continual pestering will finally make them come to their senses.

Answer: If you’ve had any problems in your own life — you needed to lose a few pounds, say, or stop smoking — think about how you would have received the “continual pestering” of a sibling on the issue.

Announcing to his sisters that he won’t help them financially before they ask may have an unintended side effect. If Mom has any money left when she dies, she may well allocate more of it to the sisters under the assumption that they’ll “need” it more because their mean old brother won’t help them.

Dear Liz: Your answer to the financially savvy brother whose advice is lost on his sisters was a bit harsh and shortsighted, so my guess is that you may not know anyone who has siblings who will continue for the next few decades to need help. It is hard to deny a sibling help while enjoying the benefits of prudent saving. It is harder to watch a sibling suffer, even if they should have avoided it. Seems to me completely different from giving advice about child rearing, which I might add is sometimes simply a statement of the obvious and one that should not even have to be mentioned, like don’t let your kids scream in public. This young man is almost certainly going to live with either guilt over not supporting his sisters when the mother dies or the frustration of having to give up hard-earned funds to avoid the guilt. You should have said he needs to write them a letter citing the guidance given and making it clear not to come to him when they get in trouble.

Answer: Thank you for providing a perfect example of why people find unsolicited advice so annoying.

The brother asked what he could say to his sisters to make them more financially responsible and to his mother to make her realize she should stop supporting them. The answer, of course, is nothing. There are no words that can make other people change unless they want to change. Since his family has made clear they’re not interested in his advice, continuing to offer it would be pointless.

The brother didn’t express concern that he would wind up supporting either his mother or his sisters. Even if he has such concerns, writing such a letter would be churlish, at best. If he’s asked for help, he can make his position known then.
