When will Obama give me all the free stuff he's promising?

Well, I voted for Obama yesterday and I'm sure glad he won!

It's not my problem that other people want to work for a living, and I have no problem with having them pay everything for me.

Obama has uplifted us all. We're to receive free phones, gas, healthcare, and everything else that most people who work have to pay for.

When do we get our free stuff? I can't afford health insurance, but I could afford to buy an Xbox, an iPhone, and plenty of weed

What will happen if i don't like the iphone 5 and want to return it?

I preordered the iPhone 5, but after reading many reviews, I'm nervous I may not like it or there will be glitches. I'm sure I will like it because I have never had an iPhone before so I can't compare it to anything. My phone carrier is Sprint. Their return policy is 14 days.
So if I take it back, within the 14 days, if there's glitches or something I don't like it about it, will I be able to exchange it for the iphone 4s? Do I have to pay any more fees? Since the iphone 5 is 199.99 and the iphone 4s is 99.99 will i get back the $100? Basically, I'm just wondering how returns work with the iphone.

Why are people so greedy & selfish?

Okay so I was just on Facebook & this girl in my algebra classs birthday. Appearently she was all pissed off that her mom bought her the iPhone 4S instead of the iPhone 5. She was bitching about how much she hated her mom & wish she'd drop dead. WELL MY MOM DID DROP DEAD. People really take things for granted & don't appreciate what they have. I really hate people.
