I'm with everyone who gets creeped out trying to shop in and select things from a Wal-mart. I avoid it whenever possible-- but lately I had to look for something for my aunt, in a local Wal-Mart, and it disturbed me a lot. Same with Home Depot and all those other places where the workers may be doing their best to help shoppers, but even they don't know where everything is or how to get to it.
Anyhow... I miss, right now, because it's a very recent actual fun memory I had from a past life-- "fun" in that life meaning that I was effectively tamping down all my insecurities and fears about the way we were trying to survive, and could pretend to ignore it for awhile-- it was just a blast, this place we went to. Entirely illegal. A boathouse, with a temporary floor clapped down over the water. Raunchy movies and entertainment, and the oddest thing was seeing one of my past-life companions, Xavier, actually looking good. It was later on he really went downhill and I had only seen him from that point of view. I don't know what to make of it, it's so unusual, almost creepy, to see him looking pretty.
There was a person we called the MC, named Dick, and he would joke about all the reasons you really wouldn't want to leave, and should stay the night, not go outside, stay and be entertained. Cost nothing to get in, which was odd, they just soaked you for anything you had once you got in there.

Very freewheeling.
I notice that many on this thread, of course, miss peace and quiet and what to them were better times. Some people in this lifetime now, who are older than I am and began their lives back when I was alive last time, insist that it was a quieter, gentler, more moral time. But it has entirely to do with personal surroundings. In this current life, when it shouldn't have been possible according to conventional wisdom, I had a neighborhood where it was safe for children to walk alone at night, and we had a great time playing games. I often see people comment about the changes in the city where I used to reside in the past life, and say that in the old days, it was sweet and good and it was safe to walk at night, and isn't now. Well... no. I used to live in the dark edges of society at that time, and in this life I have it good and easy. That city wasn't safe, it wasn't clean-- they had the cleaner, safer, better perspective because of their parents, their employers, their surroundings.
In any time period, there areas and situations and families (or lack of family) that make for miserable survival situations for a lot of the population. I can understand why nostalgia makes things look like the whole world was better, but political and personal history can really take the shine off that in a hurry.
Your point of view and the people around you, your immediate circle, make the time period for you. If you're more aware of the world at large, and can read, then the politics of a larger group might figure in. It seems to me that when history is looked at, patterns of human behavior stay pretty much the same.
I don't nearly as much miss a different, mostly-peaceful past life I had, because I am "done" with it. I had hard work at which I was extremely talented (I no longer have that talent, although bits and pieces of it crop up now and then), I was taken care of in at least some way my whole life, and what I didn't understand was mostly okay with me. There were serious problems and pain, but there really was peace and quiet, and wide open spaces, for me, and I loved it-- adored it-- and I fit it perfectly. It was easy for me. For many people, in the same time period, and in some of the same places, life was hell.
The life I miss most of the time has all the "bad" parts. Crime, horror, fear. Guilt and shame. Missing someone all the time. I miss any "bad" thing I remember because the bad was what I knew. It was all I had and for most of that life, I valued my own life enough that any thing I did have mattered to me. I miss it-- I miss the trauma, because it was all I had as the only person I knew myself to be.
