A loud neighbour in the morning is a vexation to the spirit. Simply put; A neighbour who yells early upon waking, plays loud music or even says good morning loudly actually shakes the spirit of people who are still stirring, waking up, or just relaxing with a coffee/tea/news. Loud noises can anger some people.
At 7am when I walk Noche and Nacho for their morning pee. People on their way to work say hi by nodding their head, waving or by a whisper type "buenas". IT'S RESPECT.
