When I was a child in Bangkok, we lived for two years in a big house on a small soi (side street) with a dozen or so similar houses, mostly rented to foreigners. I was seven or eight years old, and the family next door had two teenage boys.
One day one of the neighbor boys invited me over to see his collection of butterflies and moths. I had no idea what it meant to collect insects, and was horrified to learn that it involved capturing them, chloroforming them, and pinning them to boards. The boy (who seemed very grown up to me) proudly showed me the jar where he gassed them to death, and how he spiked them on pins through their thoraxes onto cardboard.
