a letter to the zoo

I told my neice today that I had weeds in my backyard that were taller than she was. She then told me I needed a llama. When I asked her where in the world would I get a llama, she said, very plainly, "Barrow one from the zoo."
"How do I go about getting the zoo to give me a llama?"
She responded again, very plainly, like I should have known, "Write a letter."
When we got home, she wrote the letter for me.

(Dear zoo, Can I borrow a llama because I have long weeds? So the llama can eat my weeds. Any color will do. From Caitlyn for my aunty Stina.)
