You lose a pair of glasses. You start off by saying:
- "My glasses could be anywhere." = I don't know where my glasses are. They could be here, there, up, down. In that room, or in another room. I don't know. The glasses are in one of those many different places.
after a few minutes of searching you might say:
"I've looked everywhere for my glasses." = I've looked here, there, up, down, in one room, in another but with no luck. Conclusion: I still don't have my glasses.
"I know my glasses must be somewhere" = They are not here, there, up, nor down, in one room or in another. But they can't have disappeared. I had those glasses just a minute ago. Where are they?
I ask my wife where my glasses are. She always knows where things are.
- "Do you know where my glasses are? I can't find them anywhere." = I've looked everywhere but I didn't find them in any of the places I looked.
My wife replies patiently
- "Yes I do, as a matter of fact, they're on your head."
In many ways they are the same thing, but the "angle" is slightly different. Responsibilities are more intrinsic, as opposed to obligations. The latter, I think, is more something you have towards your environment, society,... surrondings basically. Allow me to explain why I see it like this:
If you have children, you are responsible for them, and therefore, you have the moral obligation to take care of them to the best of your abilities.
Note that you are responsible and this results in an obligation (in this case, a moral one).
Equally so, taking good care of your kids means good education, which in turn results in your being obligated to get them ready for school, help them if they need help, and, of course, pay for the tools the need (books, bills and the like)
In that respect, responsibilities are somewhat intrinsic to life: you are responsible for your own health and well being (eg: smoking is being somewhat irresponsible/reckless towards your own health).
If you, like me, are a smoker and have kids, I'd say you are obligated to smoke outside of the house, in order not to damage their health.
Your responsibilities are yours, but they result in obligations towards both yourself and your environment, or even society.
Sure, you might be given responsibilities. At work, or by people you care about, but these situations suppose a contract of sorts: a social or legally binding contract, which implies, in turn obligations. Basically: Responsibility and Obligation "go together like Horse and carriage, love and marriage": you can't have one without the other.
The inverse applies here, too: you are obliged to obey the law, if you don't, that causes harm to the society. If you get caught, and appear in front of a judge, you'll be held accountable for your actions (you are responsible for your actions, if you're a sane person).
So, a responsibility is something you can be held accountable for. How much you actually take responsibility for thinks, is evident from how you deal with your resulting obligations.

Here's what Merriam-Webster's Dictionary of Synonyms (1984) thinks the differences are:
So MW chiefly distinguishes between the three words in terms of gentle persistence in artful pleading (coax) versus enticement through beguiling maneuvers or duplicity (cajole) versus artful or seductive flattery (wheedle). Persistence seems to be central to all three forms of persuasion, and I suspect that there is a great deal of overlap in how people use these terms in everyday speech.
