2+2=4, we hold this truth to be self-evident. Unless 2 used to be a float. Or your measurements have to tolerate a margin of error. Or you are cooking and the 2 items are different sizes. Or you redefine what the symbol 2 means. Or the objects interact oddly. Self-evident truths aren't, this should be self-evident.
You also can't compare apples and oranges. Unless you are comparing their weights. Or their RGB values. Or nutritional value.
And I think therefore I am. Unless I am programmed to respond to the question 'Do you think' with 'True'. Or I am a temporary part of a distributed consciousness. Or I am an echo of something that is already gone, like star-light does not actually mean there is still a star, and sound does not mean the instrument still exists as it once did. As a point of experiment, you cannot think about thought, by the time you have thought of it, the moment is already past and you have to take it on faith that it existed in the first place. So honestly, 'I think' therefore 'something' probably is or at some point was.
The shortest distance between two points is a straight line. Unless you are working with curved space, such as by plotting flight-paths around the world. Or you are playing Portal and the straight line would travel through a portal. Or you are talking in astronomical terms where space is distorted by mass so there cannot be a straight line.
Time is fixed. But our internal time is not, and how our brain perceives and processes time constantly changes between one person an another and in ourselves. We measure time through instruments, but we can never prove that any two devices will track time equally on an infinitely small scale (and in fact, Through the Wormhole mentions two ion clocks were synchronized a year ago, but one was set a few inches higher - which was enough to throw it off because of its distance from the mass of the Earth). And we do not really have a perception of time to begin with, we are taught what time is and we assume time changed because of how we perceive things to have changed, though we only accept that things have changed because we trust our memory to be real and that things have changed - but our own minds can not actually ever be in two separate simultaneous times so we can compare them.
So, long short, there is no truth, nothing is forbidden, everything we know and measure is just a series of useful construct to help us interact with the universe we think exists. And this is why our pants were off at that intersection your honor, and this should explain what we were doing with the llama and the tub of ice-cream. *nodnod*

float num1 = 2.5f;
int num2 = (int)num1;
(and c++ was not that strict on enforcing the 'f' rule - even c# lets you get away with it in some circumstances which gets really confusing)
