My mom held a grudge for decades against a woman who wouldn’t buy Girl Scout cookies from me (about 33 years ago). We moved out of that neighborhood 23 years ago, but if you ask my mom today, she would still be mad about it.

That one lady in a flight from Dubai that took out my luggage out of the overhead compartment and dropped it on the floor, in order to put hers in.

Downhill neighbor had a wide-open view of our beautiful lower yard. They got a barky dog that they left in their backyard all day. Dog torn down our fence trying to get out and get to our dog. We build a new solid wood fence and then they complained, now that they couldn’t see our yard, that we were spying on them from our yard. Whatever. Then they build a raised deck so that they could see over the fence. We planted a row of bamboo and haven’t seen them since.

They called the building department about our fence. The building department came out, said it was legit, and cited them for their illegal deck.

Had a neighbor who let his dog run free, it would get into our yard give our dogs fleas, eat all the food and teach them how to escape.
No matter what my mom said the guy denied his dog was getting out.
So being fed up with the situation my mom dyed the dog purple and sent it on its merry way.
The neighbor kept his dog contained after that.
* note the dye was a nontoxic semi permanent dog dye. No harm came to the pupper.
