I wonder how many of your neighbors wonder who the mystery chalker is. And how many of mine do! LOL
That is the kinda crazy cool thing about it eh...
Also, we don't know how many lives we've touched. That's why I celebrate so much when I see the reciprocity happening in your neighbourhood, like that sign that was left for you that day...or when people started leaving their own rocks! :D :D
Ikr? Me too. Every time I see it spreading like that, I get happy. ^_^
