Burnt pan

It's almost a pretty pattern; probably from peas burnt hard in little circles all over the bottom. My father stood at the sink helping me pack up when I moved out of the flat I'd shared with my partner, and lifted pans from the cupboard. They were almost all black inside like this. I realised and wouldn't have him wash them; it was my ex who had burnt them... I thought I should do it, but there wasn't time and this has been stored ever since.
