Does anyone have a real bestfriend & how could you say he's real?

I too am 29 and didn't find a best friend till I was 25. We can go months without talking to one another and totally understand why. (we are both parents)But we make sure to get in touch especially when things get us down. We work to together again, but on different shifts so we still don't get to talk much. But honestly I think of her as a sister, and her I. In fact we have more in common then we do with our own half-sisters. She truly is my best friend. And I'm glad I found her.
