When one is faced with such a troubling interaction as this - which for Nixy, let me tell you, ended in a night's stay in a bramble bush anxiously looking out for Timby - one is forced to conclude that there is something awry in the lives of Timby and Nixy.
What exactly it is, I do not know, nor have I the courage to investigate any closer. But I am confident that the mosquito is not the primary source of the unbridled panic which marked this moment forever in their memories.
"Nixy! You have a mosquito on your head!"
"Oh no, not again!"
