Past and Present

It used to be:

"If you love someone,
Set her free,
If she comes back, she's yours,
If she doesn't, she never was..."

Now:

Optimist:
If you love someone,
Set her free...
Don't worry,
She will come back.

Suspicious:
If you love someone,
Set her free...
If she ever comes back,
Ask her why.

Patient:
If you love someone,
Set her free...
If she doesn't come back,
Continue to wait until she comes back...

Playful:
If you love someone,
Set her free...
* If she comes back,
And if you love her still, set her free again...
Repeat *

C++ Programmer:
If(you-love(m_she))
m_she.free()if(m_she == NULL)
m_she= new CShe;

Biologist:
If you love someone,
Set her free,
She'll evolve.
