Popped the trunk twice, and the dang hood still won't open.

Ocassionally, I wonder if I really am fit to be driving. The other day, I was late for work, and didn't remember until on the road that A: I needed gass and B: I needed to add a quart of oil.  So, I stop at the nearby 7-11. I hurridly pop the trunk and step outside the car to begin filling.
I immediately found a problem. I'd forgotten to pop the gas. So, I unlock my car, (I locked it cause I was going to pick up a drink.) and pop the gas. Relock the door, and start to pump my gas. Once the gas is going, I walked to the hood to check my oil.  The dang thing won't open.
I go back, unlock the door, pop the trunk again, lock the door, and try the hood again. Still stuck. At this point, (it is important to know that I drive a crappy problematic car) I wonder if once again, the hood popper is stuck. It had had the problem a year ago. However, I know I need oil, so I determine to fight through it.  I unlock the door, and go to pop the trunk, and reallize what I'd been doing. So, laughing at my stupidiy, I pop the hood, lock the door, and proceed to check / add oil. I put away the gas nozzle, and got ready to fill my mug.... which was locked in the car.
Even more irritated at the repeated locking / unlocking, I retrieve my mug, fill it, and start on my way. I got about a half block before I realized I'd forgotton something.... my trunk was bobbing up and down, flapping in the wind.
