No, cant be! ;)

How can a model be "more" trusted rather then "less" trusted
in the start? I would find a simulation/or rater useless if
all it can provide is a rough aproximation of what i see of
the plastic breadborad simulation! ;)

Why bother write a FFT software that shows malfunctions?

Speaking of "really" contradiction in terms! :)) 
Who? Me or the female? :))

Unfortunately, i have to pop your baloon!

Simulation is still a bitch, no doubth!

It was kidding with Harry!
