I'm different. I will talk. I talk with my parents several hours at least once a week, and I see them regularly too. I also talk to siblings too. We get along and there's plenty of love to go around.

If I have an issue, I resolve it. I'm not one to hold a grudge. First, that's unhealthy. Second, I'm a spaniard, not Italian. I'm too lazy to hold one.

I also believe that there's a time and place for resolution, and if can be nuanced depend of the persons involved and the situation. The goal should always be to make everyone "healthier".

It's unfortunate that your brother hasn't spoke to your mom. He may regret it once she passes, and with elders, that comes sooner than people realize.
