I saw this on my short walk to the train station one morning. It started with just "Hi Tara!" A few days later, "Aaron" was added to it.
The last I checked, "Aaron" was still there, but "Hi Tara!" (together with the smiley face) is no longer there, probably has fall off due to recent rainy days. It kind of reminded me of the name one holds when trying to pick up people in airport. ^^
Side note: Garlic prawns pizza with spinach and chilli flakes is yummy!
