My first lessons in love were from my family, mostly my mother. We were taught unconditional love for family, and it is still evident in the lives of myself and all my sibilings (and their kids, and their kids).
Another example set for us was by my aunt. She would be in her 90’s by now. When she was a young woman, she passed up the opportunity to marry (which was very unusual in the 1920’s) because she was supporting and raising her four younger siblings.
Another person I learned love from was a friend of the family. This mother of 6 came to our house while our mom was recovering from a heart attack. Without asking anything in return, she would cook, clean, and direct chores for the five of us kids who were at home, as well as tend to my mother, who was bedridden for about two weeks. I haven’t seen or heard about her for about 30 years, and I think about her every once in a while.
