She was selling honeydew and watermelon (pakwan) for 35 pesos a kilo. She's also selling shrimp paste (bagoong) sauted in kalamias (I don't know the English translation of this fruit but it's sour and juicy and comes from the Averrhoa family, the likes of Carambola/Starfruit).
At first, I thought the girl was just tending the stall for his mom or whoever she was with but it seemed like, she was really the vendor for the day. I inquired about the prices (with no intention of buying at all) and later asked if I could take her picture. She smiled for the camera.
A closer look at the watermelon she's selling. I haven't seen this variety before. It looks more of a papaya to me than a pakwan. But surprisingly, the flesh is red and succulent, with lesser seeds. One thing I hate about eating watermelon are the seeds, which you have to constantly spit out everytime you eat a munchful of pakwan.
