I had my brother helping to remove a tree with a non native neighbor watching and chatting with us. Phrases like "I knew I let you live to adulthood for a reason. All that time finally paid off since I can make you pull trees and shit" and "Biggest bitch I have ever met and you gotta be my sister" were used. The nonnative thought we hated each other and actually said as much. We were dumbfounded! Of course we love each other! We're always like this, its affection. Dude just walked away shaking his head. Yeah, maybe we are sarcastic asshats.
Who said anything about it being an uncontrolable situation??? And your simple solution doesn't help the people who are still going to go to the dogpark no matter what you tell them!
