Your attitude can be described as the manifestation of your personality filtered through your current mood. It can be positive or highly negative, but it is mostly based on the behaviors of others and the situation that is happening. You may not usually cry over dropping a jar on a normal day but in the cause that you got fired, a loved one died or you crashed your car you mood and behavior is abnormal of what your personality would lead you to do. Attitude is the most outside dependent expression of you.
