I saw an ex I used to live with with his new girlfriend . I was locked up with him as a teen . When I came home , my ex told me that he had a new girlfriend . When I see them in the street , should I greet them -LRB- acknowledge them -RRB- or just go about my day -LRB- ignore them -RRB- ?
Why were some Americans shocked when I told them that I would n't like to live in the USA ?
