Obligations & Responsibilities

There is a fine line between an obligation and a responsibility in my mind. To many they seem identical and even dictionary.com uses the word obligation in the definition of responsibility. When obligation is explained and not just defined, to my understanding, it seems more like the person/thing involved is trapped. When responsibility is explained, it seems the tone is more positive and that the person/thing involved has excepted this situation. As if the choice in the obligation was before this moment or not at all and the moment of choice in a responsibility is throughout. Also, that the fulfillment of a responsibility is in a proud manner rather than the obligation being fulfilled with a despite fulled disposition. With all the burdens I have it doesn't compare to what other people have been through or were dealt. So I take on my busy, complicated, "burdened" life as a responsibility. Enjoy it as you complete it, not just in memories after it is finished.
