I've done a lot of volunteer work over the years. And sometimes humorous things happen at volunteer jobs.
One time I was working as a volunteer dealing with the public. And every person that morning that I had dealt with were all men.
So when I finally had a female customer that day, I accidentally called her, "Sir."
She didn't look masculine at all. It's just that I was so used to saying the word "Sir" that morning that I impulsively blurted out that word instead of calling her "Ma'am."
I explained that to her. And fortunately she didn't get mad at me.
Sometimes we all make mistakes...lol.
