This takes my breath away.
Last fall mom was here for a weekend visit, and we took Julian and Nora to a local festival. We found these two girls (ladies, really) doing a chalk drawing in the middle of the festivities. They call themselves: "chalk chicks". I literally stood there, amazed, mouth agape, for about 5 minutes (or long enough for mom to come back to find me, and ask if I planned to join her for the rest of the day).
What I loved the most about this, wasn't how stunning the piece itself actually was, but the fact that something so beautiful was also so temporary as it would be washed away with the first rainfall. It made me feel special just for having seen it.
