Just So

just so, this, right, justice

Mnemonic

At daybreak, you kneel to tie your shoe just so—every loop and knot precisely right. You refuse to step outside until the laces are perfect. The early light confirms it: everything is exactly as it should be. Only when the shoe is just so do you walk into the dawn.
Additional thoughts
Imagine golden dawn light spilling across your shoe as you fuss over every detail. Daybreak demands clarity; nothing leaves the house unless it is absolutely correct. The obsessive ritual of perfecting the laces captures the sense of rightness and affirmation.
Quick recall
At daybreak, lacing your shoe just so—nothing moves until every knot is exactly right.
