Description
Olga, How has our son been? I hope his illness has gotten better. My symptoms are still worsening. So, for safety concerns, we still can't see each other for the time being. I've found a job that should be able to keep our family afloat. I've always been sturdier than others, ever since I was a child. Even when I become sick, I'm still strong. So, no need to worry about me. Take good care of yourself and our kid. Kluzer
