Another sign of aging parents:

My mom tells me on the phone that she's sending me an article about a local state archaeological dig near them that my dad thought that I might be interested in, and like a week later, an envelope from them with the cut-out newspaper article arrives.

Then, like a week after that, an envelope from them with a photocopy of that same article arrives.

. . .

(??? - maybe they copied the article and couldn't find it, and so they sent the clipping, only to find the photocopy later and then forget that they had already sent the clipping?)
