Dear Abby >> I recently received a voicemail from my brother that recorded a conversation he was having with his wife. It was clear he didn’t know he had accidentally dialed my phone during this conversation. It was an argument, which lasted two minutes before there was a pause in the conversation and he hung up.

I haven’t addressed it with him yet because I am shocked at my sister-in-law’s behavior during this conversation, and the way she treats my brother. I have known for a while that she blames others for situations she should share the blame in, but I had never heard her in a private conversation until this voicemail.

My brother must know those two minutes live on my phone, although we haven’t spoken about it.

I want to talk with him and tell him that I heard what she said. I’d like him to know I hope she treats him with respect, and that she sounds ungrateful for all the hard work he puts in at his job in their one-income household with two children.

How should I handle this?

Dear Overheard >> Talk to your brother and express that the fight between him and his wife was partially recorded on your phone. Then tell him you don’t mean to pry, but think he and his wife could benefit from marital counseling if they are both willing. (I hope he will listen and have some sessions, even if his wife refuses.)

Dear Abby >> When the hostess offers you leftovers after a nice meal, how much should you take?

Dear Wondering >> Don’t be greedy. Leave enough food for other guests to take some home if they wish, and don’t forget to do the same for your hostess.
