phone conversations

I got a text message from a girlfriend in Dallas yesterday. She broke up with her boyfriend, and she sounded quite upset. So, tonight after work, I called her.
We chatted for 4 hours.
We had a lot to catch up on.
Summarized version: He was an idiot, she kicked him out.
She lives miles and miles away from me, and we don't talk very often. But I still consider her a great friend. She's a strong woman, so I'm sure she will be fine. But in the meantime, it's nice to know that she can reach out to me, and I'll be there for her, just like she's been there for me many times. That's what friends are for, right?
