Nigdy nie spojrzały sobie prosto w oczy.
Nigdy nie spędziły osobno nawet jednej chwili. Siostry.
Wspaniała opowieść o byciu naprawdę razem!

Greetings from Chelm sends Zbigniew. I already contacted you before, but there was no response.
I am gonna analize your history (your case). Reminder, I am historian at a school (SP - szkola podstawowa, elementary school).

Cheers, I am testing if the email address is working.
Cheers again.

They never looked into each other's eyes.
They never spent even one moment separately. Sisters.
A great story about being really together.

It's not Chelm, but Chelmno (the city), sorry about that.
