Cacti at school

In this week's science lessons in Wolfie's school, they will learn about cacti. I am curious about his reaction to it and he will think about them. When I was his age, I found cacti exotic and a tad mysterious, what with their capacity to survive a long time without water and to get hydrated thanks to them. My parents bought a few for me and my brothers, I cannot remember if they survived for long, we were lousy botanists. Or I was anyway. But I remember them to this day. I also remember that I asked for a cactus. I wonder if Wolfie will do like I did back then and ask us to go to a garden centre this weekend so we can purchase his own cactus.
