I believe in the power of friendship more than that of sensuality, or romantic love. There is nothing bad with those emotions either, but what I have experienced so far was that while those things might change with time, real friendships endure a lot. Sometimes they are cut off for years, and continue just as strong as before, or even stronger. I think those relationships last long which contain this element of strong friendship as well, not just affection.
Nowadays no matter where I go, there will be always friends who are not at the same place where I am. May be also because of this being able to give something what makes the other person happy is such a great feeling for me.
