Everybody will know the big changes years from now, but there are a lot of smaller details the museums aren't covering. Everyday occurrences, that are so often lost - you can name the presidents of the US, but not what they usually ate for breakfast - right?
Cats were everywhere after the event. Independent ones that escaped, or hand raised little kittens. It was really kind of symbolic of protecting and feeling like you made a difference in something's life. People would rescue cats, or try to avoid ever giving them up during the event. And of course, their services as pest exterminators was needed more than ever.
There was a lot less sweetness in cooking. Who is going to be growing sugar after all, or importing it from an island? Most people would choose sugar cane over potatoes, but we all know which would get planted anyway. And of course, no one was distributing soda, or packaging donuts - or even the ingredients to make them.
Lights after dark became hard to come-by. At the most harmless, they attracted bugs, but raiders or reanimates could see burning lanterns as well. No electricity meant alternate light sources were often fire hazards, and in ramshackle accommodations, a fire could get out of control quickly.
Guitar strings rust, pianos can't be moved, music players need batteries, and playing cards quickly get bent or dirty. A lot of common games and music just wasn't so practical.
You would be surprised how hard it was to find a working pen after a while. No one thought to grab dozens of them while running from reanimates, and they run dry, freeze, or crack. Pencils fared a little better, but more writing ended up on personal devices than parer after a while.
