It's like this
In life, there are many things that we learn by example. I think among these is how to love. We learn how to love and be loving by doing but also by the examples around us and through the guidance of those that we know and love.
It may be valuable to meet a person's friends to see what kinds of examples they offer and what guidance they give.
I count myself to be very lucky to have great examples and wonderful guides in my life.
