Suffering

There is no big suffering in the world then attachment to a thing or a person. Actually attachment oppose the biggest rule of nature that is 'nothing is permanent in the world' and if you are attached to something or someone then there is  a great chance that you are going to suffer.  Now at the same time you cannot detached a mother from her child, musician from his music and so on. So the coolest thing to do is attached to any one/thing but keeping in mind that you may lose this person or thing in future.
