Funny old man at McDonald's

When I was studying English at McDonald's as usual, one American old man came and asked me what I was doing.

He often comes here with his Japanese wife.

I told him I am going to Seattle this Saturday, then he asked me why I am going to Seattle even though it's always rainy and cold.

I said, "I know, I know..." He said "What will you do in Seattle?" then I said "I am going to Microsoft conference". Then he asked me if I work for Microsoft.

Before they left, he picked up my pencil and wrote down "天才" on my textbook. He was funny.

Note: "天才" means genius.
