If you can't be nice, at least be amusing.
As I was waiting for one site to load on my slow-as-molasses, dinosaur of a computer, I took the opportunity to go, uhm, powder my nose. As I left the room, I admonished ~K~ to leave the computer alone as I was still working. I can't tell you the number of times I've popped out for mere seconds only to return find all my windows closed, work lost and ~K~ in my chair playing neopets.
"What are you doing on it?" she asked with THAT tone in her voice. As if she knew about porn and suspected that I was downloading it. Yeah, as if I'd do that. While she was awake. ;)
"I'm waiting for a site to open that has information I want," I replied.
"What type of information?" she skeptically asked. Again with the tone.
"Stuff on fashions from the 1980s, as if I owe you an explanation," I informed her. Yeah, I was getting a tone too. And an attitude to match.
Then she moved in for the kill.
"What are you doing?" she says, "Working on your (she pauses for a beat) Halloween costume?"
