I got a whole list
It's a toss-up between:
Dumping my most evil ex-boyfriend before he dumped me (the S.O.B.)
or
Taking the job with the nice high salary, that would have required me to relocate. I later relocated to the same area, following my husband... and now, 3 years later, I'm making the salary this company offered me right out of college.
(P.S. this company is now laying people off, so maybe I'm better off having a lower-paying job than no job at all.....)
