No Harm No Foul

[Just Curious]

Ok... I obviously need help here guys and gals....
Interference.... Obstruction...
It's not about which is which... It's probably more about the subjectiveness of the call..

1. B1 hits a long ball to right field.... F3 is watching F9 chase the ball out to the fence totally oblivious to everything else, but is standing in B1's runnning path. F3 does impede the progress of B1 as she rounds 1B on her way to 2B...... Obstruction

2. R1 on 1B. The delivery and R1 is on her way to 2B. B2 smacks a hard grounder to F4. Timing causes R1 and the ball to intersect over the base path and A.) R1 leaps over the ball to only avoid contact, but impedes the vision of F4, which causes her to lose sight of the ball and the ball get by F4. B.) The ball hits R1..... Intereference

In any of the 3 cases above, none of the actions were intentional. They just played out that way. Why penalized or consider penalizing the situations....

I have seen all of these situations this season and I have a hard time dealing with them because I don't considered them intentional acts.... When the coaches want to comment, to me it's an "Oh Well" call... "Timing was bad coach, but it wasn't intentional..." What part of common sense am I missing here?
