You know you're old when...

I was out walking and passed a storefront where two employees were looking concernedly at the sidewalk.

One stooped to pick something up. The other said, "Ugh, don't touch it!"

I got closer and saw it was a freshly dead green-yellow bird; apparently just having flown into the glass.

"Look, it has a leg band!" said the employee holding the limp body.

"It's a parakeet from a pet store," said the other.

I chimed in, "More like an ex-parakeet, by Python standards."

I got two slow, head-swivel takes, followed by two utterly blank stares.

I am a fossil.  :)
