Those are disappointments (particularly the robots), but let's discuss another series of things that might have surprised us: Confusing events that happened so frequently on TV shows that they seemed a lock to happen to us as adults.
These three things were on TV so often during my childhood that at least I presumed they would happen to me:
Discovering a new student at my school who looks just like me, but wears glasses.
Here's the common plot: A "new student" appears at school who looks exactly like one of the main characters, except for the glasses (or if the character wore glasses, the "new kid" doesn't). This invariably leads to hijinks where the regular character is blamed for something he or she didn't do or the main character gets away with something that was blamed on the "new kid." At age 10, I would said there was a 70% chance that a surprising "twin" would enroll in my junior high or high school. Apparently, that doesn't happen often.
Suffering as someone uses a voodoo doll.
Voodoo was a strangely common theme on TV shows several decades ago – or at least the TV-show version of voodoo, which involved someone making a doll that somewhat resembles another person, then making the doll do crazy things that then happen to the person. Childhood Brad expected to have at least one experience where I couldn't control my limbs or when I inexplicably fell down as my arch enemy twirled a doll version of me. Apparently (fortunately), it doesn't work.
Accidentally bidding on something at an auction.
My childhood experience (on TV) convinced me that every adult ultimately winds up at an auction where expensive pieces of art or museum-level artifacts are being sold to the highest bidder. These auctions are populated by snooty people, many of them with British accents, who use slight nods to make a bid. An unintended twitch or a scratch would be seen as a bid. So was a slight uplift of an arm. At these auctions, everyone except the TV character was able to control their itching and body movement. Invariably, the main character (who never had money) ended up accidentally winning the auction, putting them in the undesirable spot of having to talk their way out of it. Young Brad was convinced he'd attend an auction and accidentally buy something. Young Brad wasn't confident he'd be able to talk his way out of it. Turns out I've never been to an auction and I've never heard of someone accidentally winning an auction.
I guess TV shows don't accurately reflect real life. Although I'll avoid high-priced auctions, just in case.
