I have my own version of carbon dating. It doesn’t require equipment or isotopes. I use life landmarks (if I can remember them). They have to be big ones like retirement, residences, jobs and definitely cats. (I lived at this house when I had Magic and Lacey. I lived at that house when I found Jake.)
Since I’ve retired, it’s often (but not always) before or after retirement.
I recently did another clothes cleaning out. I don’t buy much. I have a nice funeral dress, a wedding-attending dress (you can’t multi-function the funeral dress for a wedding), a summer dress, a jacket or two and the rest is all casual. I have long ago eliminated anything that I didn’t love or wasn’t comfortable. Everything I have from my work days I love and fits well. However, it’s all at least seven years old. Before retirement. Some a few years before retirement. Sadly, it sits in the back of the closet collecting cat fuzzies.
Styles change making donation an easy decision (I’m sure homeless people love decade old styles like shoulder pads!). I have a Calvin Klein double-breasted gabardine navy blazer with brass buttons that looks like a hundred bucks on although it predates retirement by several years. It will never go out of style. Even with that description (and run-on sentence), I haven’t actually worn it in a long time. Why do I keep it?
Some of my clothes may be pre-retirement but my desktop, laptop and Kindle are post-retirement. (That testifies to the short lifespan of computer equipment compared to jeans and tee-shirts!) My car is post-retirement too. Some house renovations were done prior to retirement. I worked longer to pay for a porch renovation that was worth every penny. The pond was pre-retirement too.
Retirement was the last big event but it’s not the only time identifier. There are more current things.
There is old gym or new gym. I have friends from both.
Before Gracie (newest cat) was adopted or when Jake (oldest cat) was alive is a big one. Life was very different with Jake. His last few years were filled with medical accommodations. Vacations were short and far apart.
I have personal medical landmarks that I don’t use at all. I keep them out of my mind. I don’t use my mother’s death either. I moved to another state a few months later making that the landmark. I don’t like sad landmarks when I can avoid them.
