Saw my sister posted Happy Siblings Day to me on Facebook back in 2020. Per Wikipedia: https://en.m.wikipedia.org/wiki/Siblings_Day, it’s Siblings Day in a few places.
I have not seen my siblings since January 2022. They are not big on talking on the phone. At times like this, I think of them and keep them in my prayers. I have three half-siblings; one died the day she was born; the other two half-sisters are still alive as far as I know. I don’t call them half-sisters in general conversation although I do for genealogy purposes. I also have a sister and two brothers.
