Ouch. At 38 years old and having never been married, I guess I should have understood that I was a spinster. Except that I didn’t.
To be a little more accurate, 40’s and 50’s is hardly “December”.
How about 60? Would that be October?
I only looked up the defination of “spinster” a couple of months ago. No kids, no husband, only cats to sleep with. Holds fist up proudly. I’ m a spinster 
And to be honest, the only reason I looked it up was because I was looking at documents that referred to the seller of property as “Jane Doe, a spinster woman”
A friend of mine is 22 dating a man who is in his 50s, long-distance. Honestly, the long-distance part is what saves it, and she acknowledges that were she in his sphere, he would easily dominate her and she would become more like a satellite. That’s not about a formula but about their respective positions in their lives.
Agreed.
