There are adults in this world who have:
- never heard busy signal
- never used answering machine
- never used VCR, or had to rewind
- never had to install an OS from floppies
@yakkoj At first I was going to say "What human adult hasn't used a VCR" but then I realized DVD was indeed on the rise in the early 2000s.
It more angers me whenever people don't know the difference between a VHS and a VCR. "Oh yeah I have so many old VCRs that I haven't seen in years" makes me want to strangle someone.
