The will it is one of those things that no one want to use or need, much less spend the necessary time to make one. It is one of those complex things, that bring a lot of feelings and that in general people simply avoid. We leave those that we love with a lot of problems trying to decided and do what they believed we had previously decided.
I remember when we did our first will, our daughter was a month old. We did it with the objective of protect her. It is one of those things that we always believe that we have more time to do and that we will never use; until sadly it is needed.
