I had a BBQ going one time and one of my friends was going through a rough patch and didn't really feel very sociable but would disappear into the woods, come back with a log, chop it into firewood and then poke the fire a bit while adding fuel.
He didn't say much that day and spent at least 12 hours just tending the fire and one of my friends who didn't know him said "Man theres always gotta be the fire guy"
It's like yea... Before we had much technology we had the fire and if we were fortunate enough we had a guy who really liked doing that. People have probably been saying something like this for a million years.
