My Dearest Richter,
My deepest apologies for the way things have worked out between us. If there are any regrets that I have in my eternity of living it is that I didn't give you the chance you deserved. However, duty comes first and therefore I chose what was the more proper decision. I do hope you understand and know you'll always have a very important place in my heart.
I always would like to have a meeting with you at some point and time where we can have a decent discussion about current affairs. There is a few things I would like to speak with you about.
Best Regards,
Calera Thatcher
