Blowing into a video game cartridge if the game isn't working

Knowing what a dial tone sounds like

Navigating a city by using a map and knowing how to do so

Having actual conversations

Old chat clients ICQ, AOL, MSN where you could ask fun questions like "asl?"

Holding and reading a real newspaper

Passing notes in class instead of texting your friends

What happens when you combine a pencil and a cassette tape e.g., rewinding your music manually

What an old-style phone actually looks like

Having colorful and numerous floppy disks piled on your desk, in your room, and at the bottom of your school bag

Having to use a VCR to record things on live TV that you want to see later

Using a phone book to look up someone's number

...and actually memorizing those phone numbers

Having countless "favorite" cassette tapes

Making a mix tape or burning CDs for long trips in the car

Having to wait many, many minutes for the TV Guide channel to scroll through the listings and sobbing if you looked away for a second and missed the channel you wanted to see
