Could be that you were only 6 or 7 years old at the time!
First, it was: "My brother once moved to a Detroit suburb and in that year they had exactly 1 day of sunshine."
Then, you say: "Hey, I was there the day after the sunshine." and "I believe it was 1971 or 1972."
Now, it's: "I have a vivid memory of the year without Sun"
Wow -- that's some vivid memory of, maybe, 1971 or 1972!
"Could be that you were only 6 or 7 years old at the time!"
Seems you're not worth a sh*t at math, either. As stated, I'm 59. That means I was aged 20 through 22 in 1971 & 1972, not 6 or 7.
As for being a "troll", I've been here approximately the same length of time as you. I've run into a quite a few breathtakingly ignorant asses in that length of time, but you're exceptional.
Keep talking, you're distinguishing yourself more with each additional response.
