Hello @blackalbino1. I like your story about you and your sister. As the oldest, she was tasked with teaching you. When you say that:
"She's my classroom, my library to learn, relearn and unlearn all I need to become that exemplary adult."
That's so special to feel that way about her. And why go through the task of teaching the same thing again. Let the older one have this responsibility and see if she's learned well.
What a delightful story. Thanks for sharing. Take care, and have a good rest of your week.
