I made an observation years ago; and now the situation seems to be getting worse. Youngsters (20 somethings and younger) brush off history. If they don't know about a particular bit of history, the phrase That happened before my time is used to sweep away any relevance of anything that occurred prior to their birth on this planet. Rather than make a notation of interest and learn of an historical event, I am met with that response. My rebuttal is Most everything happened before your time.
Look to one of my favorite sites on Saturday mornings for a fun history quiz
