Number 1 -- You are NOT stupid. The town is stupid for continuing to use those bricks in the crosswalks. There are new technologies (
StreetPrint or DuraTherm) that are safer and cheaper to maintain and look better.
Number 2 --
Number 3 -- Didn't your optometrist teach you about tipping your head down so you can see your feet clearly??
Number 4 -- You've got neuropathy and you're carrying 4 bags of groceries

Didn't know they were holding the Superman tryouts this week. Get a shopping cart or shop more frequently -- easier on your poor body
Number 5 -- I'd be making a trip to the mayor or the selectmen's office with information about a different, safer type of "sidewalk brick". Maybe *THIS* was The Universe's plan in the first place
I hope you feel better tomorrow. BIG HUGS.
