Old is as old does

Arnica ventured into the City of Chicago at un-gawdly late hours to listen to some blues. Arnica and his host found a bar, ordered drinks and settled down to watch some great music. But the following day greets Arnica with much disillusionment. Arnica was the second oldest person there, the oldest person would be the person Arnica went with.

Arnica found himself asking, "when did bars start letting in high school students?" It was then that Arnica realized, yet again, that he is very old. And so are you.
