i don't get the last sentence, what does it mean?
A delightful letter came yesterday from Griselle. She writes that she is about to make me proud of my little sister. She has the lead in a new play in Vienna and the notices are excellent—her discouraging years with the small companies are beginning to bear fruit. Poor child, it has not been easy for her, but she has never complained. She has a fine spirit, as well as beauty, and I hope the talent as well. She asked about you, Martin, in a very friendly way. There is no bitterness left there, for that passes quickly when one is young as she is. A few years and there is only a memory of the hurt, and of course neither of you was to be blamed. Those things are like quick storms, for a moment you are drenched and blasted, and you are so wholly helpless before them. But then the sun comes, and although you have neither quite forgotten, there remains only gentleness and no sorrow. You would not have had it otherwise, nor would I.
