red and...[a] feeling of weakness in the knees". However, all these symptoms vary on an individual basis, and not all individuals may experience the same symptoms. One can feel a sense of obsession over the other person, longing for "the day [when they return] to that person". One can also uncontrollably smile whenever thinking about the other person. There is some debate over whether one can artificially create chemistry if they are "not initially feeling it". While some people hold that it is something that you "can't learn and can't teach...[and you] either have...or you don't", others hold that chemistry is a process rather than a moment, "build[ing] up and adds up and eventually you get this kind of chemical bonding". Some people, while believing it is possible to artificially create chemistry, think that it is better to let chemistry hit them spontaneously. In Western Society, chemistry is generally considered the "igniter [and] catalyst for the relationship", i.e., without this chemistry, there can be no relationship. Having chemistry "can be the difference between a relationship being romantic or platonic". Chemistry "can cause people to act sexually impulsively or unwisely". It can also be the difference between someone remaining faithful in their relationship, and seeking one night stands and affairs. Dating coach Evan Marc Katz suggests that "chemistry is one of the most misleading indicators of a future relationship. Chemistry predicts nothing but chemistry." This is because chemistry can make people blind to actual incompatibilities or warning signs. Psychologist Laurie Betito notes that arranged marriages actually do quite well in terms of relationship satisfaction, and this is because "a spark can build based on what you have in common. You can grow into love, but you grow out of lust." Neil Clark Warren argues that physical chemistry is important because "couples who don't share strong chemistry may have additional problems during the ups and downs of a life together." Like Betito, he suggests not ruling someone out on the first date due to lack of chemistry. "But," he adds, "if by the second or third date you don’t feel a strong inclination to kiss the other person, be near him, or hold his hand, you’re probably never going to feel it." Although this quote assumes the other person is male, the truth of the matter is that the other person may instead be female. April Masini likewise says that chemistry is
