Everyone is a liar, a cheater, a crook to someone. That same person is a best friend, a lover, the nicest person ever to someone else. You can’t label someone as one type of being based on how they are with you. You can say that they’re a bad person to you, but you can’t generalize. Put someone in a different situation with different people and they’ll show a new side. The reverse can be true too..just because they’re a good person to you doesn’t mean they are that way with everyone. What’s even worse is that, since every human posses the potential to utilize any of these attributes, someone who is your best friend can turn out to be a liar once the situation changes. Be careful and know that every human being is dynamic. A friend I had a while back told me this: people don’t change, situations change…but people don’t. consider the situation before classifying a person and do be surprised when the situation changes…you’ll see things about a person that you never knew existed.
