After expressing his shock and difficulty in understanding the US civilization, the Central Asian apologized to Zhang Lisheng. "I'm sorry, doctor. It looks like it's my comrades who have gotten their information messed up. We have drunk too much that day and you know, alcohol makes people excited and confused. Perhaps we have mixed our real memories with the horror movies we have watched before together. I've studied psychology a little before. This is a very common memory confusion paradigm…"
"It's alright, Mr. Lucas. I sometimes would get things mixed up too," Zhang Lisheng chowed down on the pie and smiled faintly as he interjected Lucas' jabbering, "Besides, you've let me know just how 'optimistic' the ordinary US citizens are about the constant emergence of foreign worlds on Earth. To be honest, I feel much assured now."
