As other have said, very sorry for your loss and glad that it was only material possessions. Fire sucks. I was on the local volunteer fire dept for 10 years, and it is just so difficult seeing people's lives upended when something like this happens. Between that, and the accidents (automobile) that happened, I just couldn't stay on any longer. Most of the people I knew personally, it's a small community. I cared enough to want to help those in need.... but it's a double edged sword. I also cared too much to the point that after 10 years, I had to leave. Too much stress, and I had seen enough death to last me a lifetime.
We're a small town also totally volunteer. Them boys got here in about 20 mins. Might seem like a while for city folks. But it was 3 am so really for them to get out of bed get to the station and get here was amazing. And yes I know them all and they know me. Gave them all a big hug after. It's definitely tough tho because you know them. There were tears on both sides.
