Ok, so here's the deal. We have these neighbors on one side that had a history of hostility (undeserved) towards our landlords, who used to live where I live now. I can explain if you want to hear it, but just rest assured that their hostility is completely ridiculous and undeserved. Fast forward, our landlords moved out, we moved in. We've never had any interaction with these neighbors whatsoever. Last year, I came into the yard to find several lumps of raw ground beef in the center of the backyard. I picked them up before the dogs could eat them and threw them out. A little while later, I found fish filets, again, in our yard. Threw them out. Then pizza crust. Then cheese. Then hot dogs. Recently, I saw them pour water (or something) out their kitchen window. More recently, there are splashes of what looks like pancake batter on the outside of our kitchen window. Understand that I live in the city, so the gap between our houses is slightly wider than a sidewalk, and our kitchen windows just about line up. Also beneath their kitchen window (on our property), we just found a pile of polenta(?) and two peeled, hard-boiled eggs. The final offense is that they came into our yard to repost their fence - which would have been fine, but they left the gate to our back alley OPEN. I was away with both dogs at the time (luckily!), so it's possible they did try to knock and ask if they could enter the yard, although I doubt it. If I had been home and had the dogs out, and they entered the yard, I can promise they would have been charged, and possibly body slammed and bitten. Keeva is a territorial little pill when people enter uninvited, and my roommate's dog is a 75 lb GSD mix who's extremely hostile to men who let themselves in. My point is, do NOT come into my yard without asking. Ever. Now, the food thing... I think that the beef, fish, cheese, hot dogs, were only meant as treats for the dogs. The father of the really hostile man is a sweet old guy straight from Mexico. (His adult son is the real asshole in question.) I heard him talking about how much he misses having dogs, and he has told me before how much he likes Keeva, etc. I think he probably just has very different ideas about dogs than we do and thinks he's giving them a harmless treat. I still don't like it, and it needs to stop, but I think it was innocuous. The food/crap being dumped out the window, I have zero tolerance for. I think it's disgusting, disrespectful, and needs to stop like yesterday. And I do not want them to EVER let themselves into our yard without permission, much less without shutting the freaking gate behind themselves. I definitely think that they're displacing their hostility with our landlords onto us and our dogs. And lest anyone should ask, our dogs are never nuisance and never left outside alone to bark excessively, etc. I want to take care of this ASAP without further provoking them. I'm here for 9 more months that they could make REALLY unpleasant if they wanted to. I'm getting "Dog on Premises" signs for the gates, and I'm going to talk to my landlords about putting padlocks on the gates as well. The food thing... I don't know. A note? That's the only way they've EVER communicated with us before, I've literally never spoken to Angelo (the asshole) in person. I would feel SUPER uncomfortable knocking on their door, tbh. Cookies if you read the whole **** thing!
