Love and Taxis

"It is an extra dividend when you like the girl you've fallen in love with" said Clark Gable.

"Oh, Clark Gable" said Jesse.

"Is it possible to not like someone you're in love with?" we all said.

"Love is just memory and time. A collection of memories that you're fond of and like the best. You go along in life until one day you realize that there is someone who you share really good memories with, and that's when you know you've fallen in love with" said the cabbie.

"Don't overuse your brain and think love exists. It's just a word; it's not real." said the cabbie.

Space Battle

So, recently I've been watching a lot of Battlestar Galactica, and last night I watched Empire Strikes Back and I've been thinking:

Why do all spaceships approach other spaceships in the same orientation?

I mean think about it - there is no up, down, sideways, or back again in space, right? Gravity within spaceships seem to be oriented so that the pilot can sit in his or her seat, but there is not gravity outside of a spaceship. So, it would make sense to me that ships would approach other ships from all sorts of ways, upside down, sideways, any number of different oblique angles and so on. And yet whenever you see one fleet of spaceships approaching another fleet of spaceships, the ships are ALL oriented top to bottom the same way. Is this done because we as an audience member would find it weird and disorienting any other way, or have TV and filmmakers just not thought of this? Or am I mistaken?
