Example, overheard in the hall, from shiny new faculty member to a senior (in rank) one: "I don't know if someone of your generation would know this," thereby placing the senior faculty member in age as being somewhere between John McCain and Methuselah.
How is the listener supposed to respond?
It goes the other way, too, with implicit "your generation" statements:
There's a fine line between departmental history and Grandpa Stories, and sometimes one crosses over into the other.
I don't have any words of wisdom, except maybe this: when you're tempted to say something about "your generation" or to say something that starts "In my day," think again. It's possible to make a point without emphasizing the differences that divide us from our colleagues.
