Uncomfortable 30 second rule
(files.catbox.moe)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Pro tip:
Always max hot water (or hot water only if separate) to warm up shower fastest and save water. It's a win win.
Turning it 3/4 or something to desired temperature takes longer to heat up and wastes both hot and cold water.
