It is my fault. I wanted to have a bit of time to finish up some work. "I want a pen" she asked repeatedly "Fine have it." I succumbed and handed it over without even looking away from my computer screen.
The photograph probably speaks for itself. I am the bad guy for giving her the pen and I am going to be the bad guy in a few minutes when I try and wash it off of her face. Even better, they both did it. Great. Just great.
