### Shoes and chocolates

On a different note, tango led to an unusual event last night. I met a physics undergrad student. He asked why $0 + 0i =0$ and I explained it using the axioms that define a field, or more simply just a ring, which I hope was the right answer. I at first only talked him through it but when the class was over and I sat down to watch the intermediates dancing he sat next to me and I wrote it down for him on paper. I was eating chocolates, so I offered him some. He took out a huge (10cm+10cm at least) slab of white chocolate decorated with red hearts. I figured he intended to share it but I felt bad about him opening it for me so I didn't bother. I just asked if it was all done in chocolate and he mentioned working in a French bakery/pastry shop. When the explanations and small talk were done he got up to leave, but didn't pick up his chocolate, offering it to me. I kindly declined, but he insisted and said it was nothing because of his job. I said he should at least take another one of my chocolates and he said it was a fair trade and left. So now I'm stuck with a piece of chocolate I don't feel like eating (even though I've been binging on chocolate like you wouldn't believe lately). It just makes me uneasy, is all.
