Do you park there and then catch a bus? Is the disputed space somehow blocking access or visibility for the small business?
I feel like you are giving out only the factoids that make you look good and omitting the ones that tell the rest of the true story. We aren't dentists, don't make us pull teeth (factoids) one by one.
I think I was clear in my original post, but let me be more specific: It's a legit public street parking spot at the end of the street. No parking restrictions signs (time limit, street cleaning, etc), no resident permit required, no fire hydrant, not in front of anyone's house. The space is next to a windowless solid brick wall of a warehouse type business building. There are two parking spaces next to this wall. One space is occupied by a small business van 24/7, the other space in front of it is where I park. Sometimes other cars park there too, like I said, it's public street parking. I am very careful and park far enough from the street corner so no way I am blocking anyone's access. If I violated any parking rules I would have gotten a parking ticket from the city already. I park there and go to work, but this shouldn't be relevant -- and no, my work isn't selling drugs in the neighborhood or anything illegal.
That woman lives in a small condo building converted from a 3-family-house. She parks in their private parking lot next to the house and every unit gets assigned parking space. So it's not like she has to fight with me for a space. In fact there are many available street parking spaces for residents (a reason why resident permit is not required), but I just don't want to park in front of someone's house, especially if that someone is crazy like her.
So this is the true story. No more, no less.
