For those who never had siblings

Odd how things go. Mum had a baby brother by 13 years.
I have an older one by 6 years. War separated brother and I.
Mum was never close to her brother. She was going through an education system far different if at all to her brother.
Similarly I was starting high school when brother was university.
Watching our 4 close siblings grow up together and the bonds they forged is fascinating and heartwarming.
Something I'd never experienced.
In later life age difference wasn't an issue just the distances between each of us.
