monstre terrible

Everytime, when I want to work on my computer,
Tommy jumps on my buro, meanwhile loud snorring,

Then he walks on my keyboard, to get my full attention.
Other programs suddenly start up, or keys are pressed,
like thissssssssssssssssss.
If that does not help, cause I try to manage around him,
he ends up sitting on my keyboard , even louder snorring& purring.

He's a 'monstre terrible'!
