At age 65 there is still much to learn and much to be reminded of that you learned before.
Sugar vs vinegar. As a recovered Type II Diabetic I avoid sugar. I like sugar but I also enjoy sour, so vinegar is a nice addition to some foods. But in conversation with loved ones, sugar seems to be a necessity. Vinegar in conversation can sour relationships.
I’ve been rightly reprimanded for the high vinegar content of my posts. So, at age 65, I am still maturing.
