Family

I have been thinking a lot about my family. Growing up some of us were close, and some of us weren't. I had always hoped that one day we would all be close. I have 2 bio brothers, and one step sister. I have always gotten along with all my siblings, but some of them don't get along. I mean they can, but you know there are issues.
I have just been feeling like my family is pulling apart. And it makes me sad.
I see one of my brothers almost every day, and if I don't see him I hear from him.
My other brother I see maybe 3-4 times a year.
My sister I see maybe once a year, and talk to her maybe 4-5 times a year.
This makes me sad, we all have kids that get along great and would love to hang out, but it hardly ever happens.
I know that we are all busy! but come on, Family is important, and they need to feel like they are.
I think it is harder for my dad and mom, they wonder if some of my siblings are ashamed of them, or embarrassed by them.
When my dad asked me that question, I just told him that I didn't even need to think about it, and out of all the kids why ask me.
