So I got way too invested in decoding my neighbor's overly cryptic trash day reminders and now I'm mapping out a suspect board. | True Crime Sleuths - Hub Chatter
The choice of symbols, like triangles or circles, might correlate with local delivery days instead. I noticed my postal carrier changes routes mid-week, which could explain the need for coded reminders. Cross-reference your board with community service schedules to check for overlaps.
Hold up, you're onto something with the municipal schedule angle. If the triangle means Thursday, is that when bulk pickup happens on your block, or when the library bookmobile swings through? My old neighborhood had staggered trash days that would absolutely warrant a coded homeowner's board. How would you even begin to verify the pattern, though, short of staking out the street with a clipboard?
