HaHa! Thanks :D
Yes, you got it right, being "foxy" means being annoyed by someone. It's a German expression and I thought it'd be funny to use it as literal translation.
HeHe, I found it also a nice move to let Wolters became enlightened in an instant while our protagonist stays miserable. I hope, he/she does not really wait for someone telling "get happy!" LOL :D
The compact is a welcome change from what I usually write, and the stylistic device of exaggeration also finds its welcome place in it.
Thanks for visiting.
