Alpha Neighbor part deux

I got home from dropping little kid off (a not even 10 minute journey) to find a bag of dog poop in my yard.

At first I was pissed. Then I was worried. I had let the dogs out for a few minutes right before leaving to take little kid--could one of them possibly have pooped in someone else's yard? Murphy is on a long leash type thing and can't reach the property lines. Lily goes to the bathroom in the exact same spot every time, never leaves our yard and was right at the door waiting to come in so I didn't think so, but maybe?

I sat here freaking out about it and feeling terrible. No matter what, one of our neighbors clearly must hate us to be leaving bags of poop in our yard. I briefly thought of the Alpha Neighbor but I haven't seen her lately. She changed her like-clockwork walking times so our paths don't cross; I took this as an admission that she was wrong to use my yard as a dog poop depository. I felt triumphant about that situation and have been commending myself for calling her out on it and resolving it quickly.

I decided to take a shower and as soon as I was naked and all oiled up, water running, I heard a knock on the door. I chose to ignore it and then thought that it may be the new poop-leaver and that I better figure out who it was so that I could go to their house and apologize profusely. I peeked through the blinds and see Alpha Neighbor's two fat, furry dogs waddling around my yard.

What the hell is this woman's problem? Okay, so you somehow don't know that people may not want you to leave bags of dog shit in their yard, even temporarily. Once someone TELLS you not to leave bags of dog shit in their yard, even temporarily, YOU STOP DOING IT. Leave it in someone else's yard if you must. I know she did it because she didn't think I was home and this pisses me off even more. I live on a heavily populated street, there is not one good reason that I should be the dog poo drop off station. I cannot figure out what her problem is.

I wasn't about to towel off and get dressed to hear her explanation or apology or whatever she wanted, so I ignored her.

I have no idea what to do about this lady, though. I'm seriously considering running one of her dogs over next time I'm driving and see them out sashaying around the neighborhood--I don't know how else to get my message through to her since shouting it across our neighborhood (and plain old common sense) doesn't seem to work.
