My wife and I are the same age but I started using the internet around 1999 whereas she didn't use it until many, many years later.

It's fun because I can show her old memes for the first time. She missed the entire "lol so random" era of internet memes (think things like badger badger badger, "my spoon is too big", forehead shavecut, animutations, etc) and doesn't quite understand it. It's all we had back then!
