This is kinda hard to understand.. cuz he is spanish and I talked with him in spanish.

The story is this: I agreed with him to sell him some cooked lobsters, but later I said "no". He said "I hope you and your family die of cancer". My cousin has cancer so I told him and I also told him "I don't care what you say, he will get better. People like you should die, not him", so he answered "Well, he is going to die". He also used insults like "Motherfucker", "Son of a bitch", etc.. all of course in spanish language.
That's it.
