There is an actual rule of rounding that if you are rounding from a 5 you go to the even number
This is a weird rule. Is it new? Did I forget something this big?

Well not canonically, no, but this is transformative fiction.

It's five thousand for kissing, ten thousand for snuggling... End of list.
OK, thanks for the clarification Jesse. I have never heard that before and am suspicious without someone explaining the rationale.

I am a woman of various inclinations and only some of the time are they to burn everything down in frustration
I can't find any confirmation of my rule, but it's what I was taught. If you always round 5s up, you introduce a bias that is eliminated if you round to the even number, because half the time its up and half the time its down.
Aha, found a reference. Microsoft calls it Banker's Rounding: Banker's rounding rounds .5 up sometimes and down sometimes. The convention is to round to the nearest even number, so that both 1.5 and 2.5 round to 2, and 3.5 and 4.5 both round to 4. Banker's rounding is symmetric.

This site agrees with -t.
I guess the rational behind this is not to round always up if it's in the exact middle, meaninf 5. Rounding always up will eliminate the "half" nature of that 5, so you have to divide to cases in which you round up and cases in which you round down. I have no idea why the evens get the special treatment, though.

Banker's rounding hurts me. In which arenas is it applied?

OK, this seems like a good rationale.

Sometimes I trip on how happy we could be.

Well, banking for one. That makes sense, really -- especially if you're dealing with .05's of a cent and whatnot.

This is why rounding numbers is evil. Better just to live with the fractions!!1!

Get the fuck out of town. Any others? I mean, is there a reason for it to be applicable to GPAs?

I don't think rounding is always evil and the irrational numbers support me in e-mail.
