When do we learn the difference between pleasure and pain - Between love and hate or simply good and bad? We don’t, as people, have fixed boundaries and restrictions as we oh so wish, dream or believe we have.
One can say one thing and mean the other, get one thing and still want the next. In this day and age, one may never be too sure of oneself. We have gone from trust and assurance in self to having barricades on pointless items because we think that is supposed to be how we feel and live, how we are free.
But the main lesson to be learned is up to you to create. So you can differentiate everything, including yourself. Then you can stand out and be who you know you really are.
For you are one of a kind in a full house. It is about time you started acting like it.
