This quote is so powerful. Sorrow lies in every soul, we all have our silent cross to bear. Your friend must have a tough mindset, to have to cope with a horrible situation and yet to put on a smile at the end of the day.
Light and darkness is the way life works. We can't have only one of them. I think that with time and wisdom we learn to treasure the sorrow and take the lessons out of it, like a precious nectar.
She is a strong person, probably far stronger than she even knows, but she doesn't smile every day. I don't blame her. She tries to find some light though, and I think she does a pretty good job at doing so. Sometimes the shadows close in but she keeps a flame burning and works to increase its small light little by little.
By what I read she must be a strong woman, I admire that! A person who can find the power to smile through severe adversity has amazing resilience.
Have a great weekend, it is coming!
