if Trice thinks you both are pathetic, I think you both are pathetic

also, Trice, can pass by you vector's learn a language thread and explain me a grammar question? Or you can just answer here too

I didnt know of this "both is" thing, then I went look after some explanation. As it seems, "both is" and "both are" are correct but they say it depends on context.
I still dont fully understand though, help?
