yes, but its the unknowns that will get you killed. it really is easier to ask forgiveness than permission.
if some guy busts through my door i will yell at him to get out, i dont care if hes drunk, drugged, down on his luck and needing to take a [censored], whatever. if i have clearly made it a point that he is not wanted in my residence and he decides to ignore it, im letting something else do the talking. and he wont feel good. i dont care what his story is.
true, maybe afterwards i will feel bad, regret it, or whatever. but that will not change the fact that i considered what i was doing to be right at the time. none of us can afford to live in the past and dwell on mistakes.
