This is the actual story of Shrack and Princess Fiona.
Only with a much different story line from the original Shrek .

When we said goodbye this afternoon,
I was determined that this would be the last time we meet.
Until she made me promise that we'll meet again after I return.
Should I keep my promise?
Or should I just forget about it after today,
because self-preservation theory says
"It is better to reject before you are rejected." ?

I asked someone Why (are we still friends)
She said Because ('we' are not meant to be)
Hate that line, perhaps because it's so lame yet true.

Sven's line on the alternate reality is much better.
Say it again, Sven, don't let me take the credit.
