I think that with 6 billion people in the world there are multiple people that would fit someones idea of perfect. the thing is when someone finds a girl who's perfect they stop looking and wont notice anyone else who would be perfect so they think that there is only one true love. also anyone who says that someone is shallow for caring about looks if full of shit because a part of attraction is that they attract you by looking good not by making you want to vomit uncontrollably.
