It's strange to meet people in this age who are still living without electricity (small island in the Philippines). When asked, their request was for a solar powered lantern. Kids wanted colouring books for learning English.

Wow! I hadn't thought of that. I see they sell solar powered lanterns at Walmart. We can send them some solar powered lanterns, pastels and coloring books for spring festival!
