I started my second semester of college last week, and one of my classed is called Engineering Physics, keep that in mind.
Anyway, we are all standing around for about ten minutes after the class is supposed to start. Then the professor shows up and everyone crowds around the door. But we all need to wait for awhile because the professor is having trouble unlocking the door!
I just found it amusing that this is the same professor that will be teaching us mechanic this semester.
