Breakup Science
PSYCHOLOGY: Girl accuses guy of just using her as a substitute for his Mother.
SOCIOLOGY: Each claims to have been oppressed in the relationship.
ARCHAEOLOGY: One tries to bury the past, and accuses the other of trying to dig it up.
THEATRE: 'OH! Life is... ENDED... as we KNOW it!'
BIOLOGY: 'You just wanted to get in my genes!'
PHYSICS: Both resign themselves to the fact that what goes up must come down.
BUSINESS: Both decide that they're spending way too much money together, and that it's simply cheaper to be single.
HISTORY: Each party argues the breakup was caused by something the other party did in the past.
GEOGRAPHY: Both people decide to simply move far away to avoid each other.
ANATOMY: 'I never liked your body anyway.'
ECONOMICS: One party demands more than the other can supply.
for a minute there, i thought this was a serious talk on science...hmm, i like the anatomy version....IAST....
For PHYSICS I would suggest: Both decide that their relation is only relative and subject to fluctuations on an elementary level.
