Greetings, dear reader! Detective Pux here, and I'm back with another mystery to solve. This time, we're going to take a trip down memory lane and talk about the items that our parents knew but are no longer around anymore. So sit back, relax, and let's dive into the past.

1. Record players - Remember those big, clunky things that played vinyl records? Our parents sure do. They were the height of music technology back in the day, but now they're just a relic of a bygone era.

2. Rotary phones - Before the days of touchscreens and voice-activated assistants, we had rotary phones. You had to spin a dial to input the phone number, and if you messed up, you had to start all over again. Our parents were pros at using these things, but they're practically antiques now.

3. Typewriters - Before the days of laptops and tablets, we had typewriters. They were loud, clunky, and required a lot of muscle to operate. Our parents could type up a storm on these things, but now they're relegated to museums and antique shops.

4. Polaroid cameras - Instant gratification was a lot harder to come by back in the day. Polaroid cameras were a game-changer because they allowed you to see your photo right away. Our parents probably have a few old Polaroids lying around somewhere, but the cameras themselves are a thing of the past.

5. VHS tapes - If you wanted to watch a movie at home, you had to pop in a VHS tape. Our parents probably have a whole collection of these things gathering dust in the attic. But with the rise of DVDs and streaming services, VHS tapes have become nothing more than a nostalgic memory.

6. Walkmans - Before the days of Spotify and Apple Music, we had Walkmans. These portable cassette players allowed you to take your music on the go. Our parents probably have a few old mixtapes from their high school days lying around somewhere, but the Walkmans themselves are long gone.

7. Floppy disks - If you wanted to store data on your computer, you had to use a floppy disk. These little things were prone to getting corrupted or damaged, but our parents knew how to handle them with care. Now, with the rise of cloud storage and USB drives, floppy disks are a thing of the past.

8. Cathode ray tube TVs - Remember those big, bulky TVs that took up half the room? Our parents sure do. They were the norm back in the day, but now they've been replaced by sleek, flat-screen TVs.

9. Film cameras - Before the days of smartphones and digital cameras, we had film cameras. Our parents probably have a whole stack of old family photos that were taken with one of these things. But with the convenience of digital cameras, film cameras have become a thing of the past.

10. Encyclopedias - Before the days of Google and Wikipedia, we had encyclopedias. These thick, heavy books contained all the information you could ever want or need. Our parents probably had a set of these on their bookshelf, but now they've been replaced by the internet.

Well, there you have it, folks. The items that our parents knew but are no longer around anymore. It's funny to think about how quickly technology advances and how quickly things become obsolete. But hey, that's progress for you.

As for me, I'll stick to my trusty smartphone and laptop. I don't think I could handle the frustration of trying to use a rotary phone or typewriter. But who knows, maybe in another 20 years, we'll be laughing at the technology we use today. Until next time, stay detective-savvy and keep solving those mysteries! And don't forget to appreciate the past, even if it's just for the nostalgia. Who knows, maybe one day we'll be the ones telling our kids about the obsolete technology we used to know.
