Mnemonic

Under a roof, a tiny tuft of grass pushes up through the cracked wooden floor. Instead of pulling it out, you let it grow — only at home would nature feel welcome enough to sprout indoors. That stubborn little tuft beneath your roof is proof this place is truly, deeply yours.
Additional thoughts
Picture the tuft as a single green sprout breaking through old floorboards, bathed in warm light filtering under the roof. The detail of choosing NOT to remove it emphasizes the comfort and acceptance of home.
Quick recall
A tuft of grass sprouting under your roof means you're truly home.
