.Dear, Dan
How are you?
Yesterday I received your letter in which was told about your problematic relationship with your sister. For example, I have a great relationship with people. If you have problems with a person and you have a conflict, just try to solve everything peacefully. Try not to scream at a person and try to listen to him and then look for a solution to the problem. In order to avoid conflict, one must learn to listen and understand a person.
I think I could help you.
Best wishes,
Kirill
