A few days ago I saw that I had a slightly flattened tire on my automobile. I took said automobile to the gas station at Main and Wm and put air in it. The air thingie didn't have one of those built-in pressure gauges (which are no doubt terribly inaccurate but Good Enough For Me call me a bad car steward fine that's fair) so I dug into my glove compartment and found that I did indeed have a tire gauge.

So I had the gauge in my pocket that night and took it out again the next day in case I needed it to re-check the tire, but the tire looked fine. It continues to look fine, but I continue putting it back into my pocket rather than back into the glove compartment. (Yes "glovebox" is shorter but I don't like "glovebox" or "glove box" as much.)
Having the tire pressure gauge in my pocket is good. Not quite a worry stone, but maybe sorta like that. A talisman more than a relic. A symbol (anything could be) and a comfort object. And a tire pressure gauge above all those.
