The aunt who spoke about the vegan issue with her pots and pans said that the it took place 4 years ago when BK and his father were staying at her home as they had gone to Nevada for a funeral and stayed at her place. During that visit, she said that is when the issue came up about her pots and pans and BK's dietary/cookware issues.
So he was 24 years old not a teen as I had suspected. Why did he need to stay with relatives vs just staying at his own home?
