Good question. I'm still not entirely clear about that myself, but I'll do my best to explain - if I can.
SIS's ex was not a professional chef, but he WAS a gourmand and an excellent cook. The times I visited he made fabulous gourmet meals (the only annoying thing was that he was food police, too, so he portioned out VERY limited amounts and would take away your bowl/plate before you finished because he wanted to ensure that as a guest you don't eat too much, because if you're bigger than a size 0 you're way too fat and surely you will die from obesity. That went over REALLY well. Anyway.)
So every now and then SIS and/or her ex would acquire very expensive kitchen equipment. I believe the cutting board was purchased by SIS, but it may or may not have been a gift. In any case, once the divorce got ugly, they disputed ownership of EVERYTHING. They both stayed in the house during the divorce even though he was already living with his new fiance. One morning, SIS came into the kitchen while her soon-to-be-former adult stepson was using the cutting board to chop something for an omelet. (He was attending school at a cooking academy to become a professional chef at the time but still roomed at home.) Enraged, SIS told him to stop using HER cutting board and give it back. She physically tried to take it from him. They struggled over it, and his elbow was nicked by the cutting board during the struggle. Because it was bruised and there was a teeny-tiny (according to SIS) little cut, that was enough to qualify as an injury. So ex called the police and she was arrested and charged with domestic violence and spent the night in jail. Probably because the last time the police showed up (during the divorce they each called police on several occasions during arguments) they said the next time they had to come out SOMEONE would be leaving in the back of the car. So....she did. I guess because there was an actual physical injury resulting from a dispute it was enough to arrest her. And then she was required to do several hours of anger management.
I guess everything is fine now though. Years later, she purchased her former stepson's engagement ring for his fiance as a "gift." So, they're good. Even though they don't talk to her anymore and she wrote the ring off as a gift even though it was supposed to be a loan, which the guy never repaid. I guess people DO learn after a while.
But yeah, that was the saga of the cutting board.
