What a lovely post about your little sister. I am glad you were able to be there for her through all her trials.
I was 9.5 years old when my youngest brother was born, the last of 6. I have spent the last week getting to know him again, after decades apart. He was my “baby” when he was little. But life pulled us apart for decades when I was 17.
I knew you came from a big family also, so I know you really get it.
How wonderful to reunite after so long, no matter the past share the love, life is too dang short.
Be well my dear friend.
