Bug, warning me about... Something. I don't know what, but we had to have a fire drill to calm down (where I make the danger call and we both run to the bathroom to hide for a minute before I declare it's safe and we can calm down again).
I like making random noises at my dog and watching her turn her head in confusion. I just know she's thinking "what the hell is this idiot doing" and I think that's beautiful.
