Old people stereotypically tend to say "back in my days..." (I say "sterotypically" because I don't think I've ever seen an actual old person in person say that or "when I was your age...", though I like to use those terms despite not being old yet), but when were an old person's days? And what makes it their days, anyway? They tend to stereotypically use "back in my days" and "when I was your age" interchangably, so is their "days" really the time when they were our ages?
In the 1970s there was Happy Days, set in the 1950s. In the 1980s there was The Wonder Years, set in the 1960s. In the 1990s there was That '70s Show, obviously set in the 1970s (well, maybe not so obviously... It could have been the 1870s or 2070s). And in the first ten years of the 2000s, there was Everybody Hates Chris, set in the 1980s (that same decade also brought us the less-successful That '80s Show). Now that 2010 had passed and we're four (going on five) years into the 2010s, when is there going to be a sitcom taking place in the 1990s? Or has there been one undetected by me?
