People always want to associate certain occurrences happening to give reasons as to why some things turn out the way they do. I'm sure miscommunications, things breaking down, or lost objects happen outside of the retrograde, so what's the excuse then? I’ve also known people to get overly tied down by things like this and not living their lives by staying at home. It’s just ridiculous imo.
If you never knew about some retrograde before you heard about it or it became known to you, most of us would have never associated occurrences happening due to the retrograde to begin with.
