Many years ago now, I was in the states (before I leart to speak American) and said to a co-worker "I'm really pissed". About 30mins later he came over and asked what I was upset for

Once, way back when my American fu was not as strong, I had a whole conversation in which I only realised later that we were talking at cross purposes: "I had a big party last weekend," this American chap said, "my neighbour was really pissed." -- "Oh, really?" -- "Yeah, she called the cops in the end." -- "Wow, she really was pissed." -- "Yeah."
