Here are some other obsolete items. If you're of "a certain age," you may remember them:
Rotary dial phone
We had only one phone in our house, and it stayed in one place. When we got phone jacks and could move it around, we thought we were sooo modern. And our phone number had only 5 digits; my father's business phone had 4.
We spent many summer evenings at the drive-in, the best place to cool off after a scorching Texas day.
And finally, stick shift cars. Of course, they're still around, but many people don't know how to drive them. I don't know if this is true or an urban legend, but someone told me a man got out of his car to check his mailbox and a guy jumped in to steal the vehicle. 30 seconds later he jumped out. It was a stick shift and he didn't know how to drive it.
