Uncomfortable 30 second rule
(files.catbox.moe)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
If your hot water line comes from [wherever, in my case the basement] and passes by your shower before leading to a sink, it's likely that the water by your shower will also be hot once it comes out hot at the sink.
It might be! I'll try it, thanks!
