So, i was waiting at the bank for this and that reason, and then some old man approached me to help him to fill some forms (He left his glasses at home). When i get to it and ask him if he have a wife, he says "Yes, her name is [Name], my sister". The guy not only have a sisterwife, but also a son and a daughter, which are 51y/o and 52y/o respectively. This happened yesterday and i forgot about it before posting it here, and i thought you guys would find this stuff interesting.
