I dunno.
I feel the same way about those proof-of-insurance cards one's required to have in Nebraska.
I get a new set of two of them every six months.
One is supposed to keep one in the vehicle, and one in one's wallet.
I get them, toss them on the dining-room table, figuring I'll do it later.
But I never get around to it.
And so those rare times I'm stopped (for non-penalty things; I've never had a traffic ticket in my life) and asked to show my proof-of-insurance card, oops, it's a year and a half or somesuch outdated.
And so the policeman gives me a postcard, after which I show the current card to the county sheriff, and the county sheriff then signs and mails the postcard.
It's not a big deal, really, but I wish I could remember to replace the cards when a new one comes.
I think it's because the less one uses something, the less important he thinks it is.
