True things you told your folks as a kid that they *never* believed

I remember trying to explain to my parents that on Ordnance Survey maps there are paths shown that are not public footpaths (such paths are represented by a line of black dashes, as opposed to the green dashes of public footpaths), but they wouldn't have it and insisted that any path shown was a public right of way.

I am now picturing dubmill's folks being confronted by an angry farmer with a shotgun shouting "Get off my land!" to finally disabuse themselves of that particular notion.

"But HE started it!" And it was true; he DID start it.
