Input: Consider Input: Person1: What's wrong ?
Person2: I have a headache . These past few days I've been living off painkillers . Man , I feel like my head is going to explode .
Person1: You should get acupuncture treatment . My mom was always having headache issues and it was acupuncture that cured her .
Person2: The results are too slow . On top of that , just the thought of smoking needles poking into my flesh frightens me .
Person1: They don't just randomly stick you , they find your pressure points . The heat allows the body to immediately respond to the treatment , restoring the body's " chi " .
Person2: But I get scared the moment I see a needle . How could I stand having needles in my body for hours on end ?
Person1: The needles are very thin , and as long as the doctor's technique is good , and the patient himself is relaxed , it won't hurt-on the contrary it will actually alleviate pain . Now there are high-tech needles that are micro thin ; they don't hurt at all . However , if you are really scared of acupuncture , scraping or cupping are also options .
Person2: Scraping is too terrifying . When they finish scrapping , your body is all red , as if you were just tortured . Cupping is the same , your body ends up with red circles all over . It looks like someone beat you up .
Person1: This only signifies that the toxins have left the body . Actually , there is only discomfort during the treatment process . Once it's over you feel very comfortable .
Person2: Chinese medicine is strange . The patients are already ill , and then the doctor makes them suffer more .
Person1: This is the only way to get at the problem . Anyway , if you want to relieve the pain , you are just going to have to be tough and do it .
Person2: Forget it . I don't want to inflict any more pain on myself . In a little while I'll go and buy some more painkillers and take a nap .

Input: Consider Input: Person1: This is the good life ! We have it good don ' t you think ?
Person2: Yeah of course ! Although , don ' t you ever wonder what " could have been " ?
Person1: What do you mean ?
Person2: Well , sometimes I think of how things could have turned out if I had done things a little differently .
Person1: For example ?
Person2: Like for example , if I hadn ' t studied architecture , I would have become an artist like I wanted to .
Person1: I see . Yeah now that I think of it , I wouldn ' t have gotten married if I hadn ' t moved to this town and met Sally .
Person2: You see ! Everything happens for a reason ! We wouldn ' t even have met if I hadn ' t been in that car accident ten years ago !
Person1: Well , I have no regrets !
Person2: I ' ll drink to that !
