Change grows forward out of understanding
Many among us believe that most people are unable to change (for the better)..
Talking about actions of the past or experiences within a friendship, most people will always relate someone to the past of that person or to own past experiences. In case of experiences you might not even give someone a chance in a way you still have to overcome that trauma of your past.
My message here is that in some cases people are really able to change in a way someone actually seem renewed. This is possible, because real change will always grow forward out of understanding.
Communication for instance, is really coming to its potential regarding guidance and explanations. So the moment a situation is really understood (and felt), change can really happen. The world is not made in a day, so keep in mind to always be patient with one another.
