My father, a retired factory worker, keeps reminiscing about the "good 'ol days" of his younger years.
Then without skipping a beat, he'll say something like, "but it really isn't so bad nowadays."
Then he goes right back to how nice he had it as a teenager back in the 60's.
Then, right away it's back to the present, with "but technology today makes everything so much easier."
It's back and forth, back and forth from the present to the past, past to the present.
"You know dad," I finally told him, "you're nothing but a baby boomerang!"
