Former husband of his sister:

The sister of my ex-wife.
She has a child she gave birth to very early, at 16 or 17.
I never had a normal relationship. At the age of 50, she met a normal man, with whom she even married.
She divorced and fled as soon as he got to the hospital.

The fact that she has never had a normal relationship by the age of 50 has already characterized her in a certain way. But only her, not the whole floor in general.
