Dear Eric: Nearly eight months ago, my 81-year-old brother lashed out saying hateful and hurtful things about our youngest sister. At the time, I suspected he was drunk and probably frustrated from the repeated episodes of our sister’s illnesses and problems, some of which have been caused by her own serious eating disorder, depression and occasional binge drinking.

I have never mentioned the fracture in our relationship to our sister and am grateful that they continue to have some sort of relationship.

Recently, my three nieces and I planned an “aunties” visit. Before their arrival, my brother texted me with thanks for inviting him to join us for dinner and games, but we neither shared our plans nor invited him. My sister, in ignorance of the rift, told him that our nieces were coming to town.

My wife and I are at a loss. We can request that he explain his side of the silence or apologize for his hateful words. But truthfully, his apology won’t erase the vehemence of his words primarily directed at our sister. I don’t ever want her to know what he said.

I understand that it takes much courage to admit one’s failings. I recognize how powerful it is to show grace when it’s easier to cling to resentment. But my brother’s actions have been speaking volumes. I could use some advice because I’m pretty sure my nieces will ask about their uncle, and I have already spent too much time fretting over his text.

– Not Invited

Dear Invited: Whether motivated by alcohol abuse, frustration or anything else, your brother’s vitriol wasn’t appropriate, and you don’t need to stand for it. It’s perfectly fine to reply to the text by telling him that you, your sister and your nieces made plans and that you’d like to stick to what you’d planned. He doesn’t get to dictate the terms of your get-together.

You can also let him know that, while you appreciate him reaching out, the two of you need to have a conversation before you can socialize again. This isn’t meant to punish him, rather it’s a way for you to hold a healthy boundary.

You can also tell your nieces and your sister that, should they ask. If you’re aware of these traits of his, then they likely are, too. Even if they aren’t, it’s sometimes better to be honest and succinct rather than grinning and bearing it. Tell them, “we’re not in a good place right now and I hope that he’s able to work on it with me. I don’t want this to cast a pall over our weekend. People don’t always agree, but I’m not asking you to take sides.”
