The wrong assumption is when we assume that the things we experience now will be the same in the future. The most erroneous assumption is when we think that people we are now with will stay with us and will do what they are doing at the moment.
I met many people in my life. But I am not loyal. Not for those who get used to my presence and take it as a certainty. Because, behind that attitude, always comes a lack of respect, indifference... The indifferent people simply have no volition which is the base for love. And love is something that interests me the most.
Make no mistake, the love doesn't mean someone has feelings towards me - though this is a very important factor. The love means we give to each other things that are necessary at the very moment. Sometimes, even the strongest feelings succumb to very weak will, yet, the people around me tend to think that I won't bother the poor quality of their behavior. Well, it does bother. And I don't have to stay.
