Are you brining foreign flora or fauna in the country?

I recently planted a garden with the help of a seven year old named Agnes (Aggie). I don't seem to have much of a green thumb as I planted beans, radishes, and potatoes, but only the potatoes and beans sprouted. Potatoes actually sprouted where I planted radishes. What's with that? Then, I watered the beans to death (something Agnes watched me do, but didn't warn me about). Now the potatoes are being devoured by bugs so I decided to get a chameleon.

Funny thing about chameleons is that they're difficult to see and no one would agree to bring me one. I had a stroke of luck one day when I found my students scaring each other with a stick and went to see what was going on. There was a chameleon on the stick so I asked for it after explaining my predicament. They said I could have it so I grabbed it and put it on my sleeve. Everyone gasped and some of the girls said "Put it on your head" to which I responded "Say it in English, first" (they actually said "weka kichwani"). I felt pretty proud of dodging the possibility chameleon poop in my hair and went home to put the lizard in my garden. I ran into Aggie and asked her why Tanzanians are afraid of chameleons (they aren't poisonous). She told me "If one gets on your head, only your father's sister can remove it. What if your father's sister lives far away? Then you have to ride on a bus with a chameleon on your head."

At least it would be easier to sneak on the plane than other reptiles.
