I enjoy the off topic posts and links that are presented. I get off topic all the time. Sometimes I wonder if I have ADD because of my thought patterns. Jumping from topic to topic and not going back to the original subject. This happens to me as I communicate face to face with others.
My mentee and I are bad about doing this off topic thing. We could talk for hours and cover many subjects, even though that isn't why we met for coffee to talk about a certain subject.
Feel no guilt. I accept any communication. LOVING IT!
