For the past few hours I've been sure that I could smell something…weird…but so faintly that it might have been sweat, or something coming from the outside.
Just went to check the gas canister that was connected to my blowtorch (figured I use it often enough that I might as well keep it on) and the flow wasn't at absolute minimum — but not high enough to make any sound either.
Might've been that.
Huh.
