You learn something new every day, whether or not you realize it right away. There are no exceptions to this rule.
Today I learned the difference between bowler hats, pork pie hats and fedoras. Before today, they were all just fedoras to me. It never occurred to me that all three of these different hat styles had different names.
I also learned that Roseanne is Jewish, and that gummy shot glasses exist.
It doesn't have to be anything life-changing or significant or anything, just something that you learned. So AG, I ask you now, what did you learn today?
