I don't miss dial-up internet, I just don't. I don't even like the sound because it's just digital screeches and it's a sound that makes me cringe a little upon hearing it. Because I remember the times when I'd be listening to music with headphones with volume high and then that fucking digital screech just blares into my ears.
I don't miss waiting 30 minutes to load a page. I don't miss a bit of it.
Gay jokes on TV. You know the kind. "it's funny because it's gay", very prevalent on series like Friends. Friends is a great show even today, but I do not miss the gay jokes.
I love monty python's flying circus, but they had multiple sketches across several different episodes where the punchline was a gay person getting murdered. Kinda hard to watch some of them now.
