My guess is that Object Oriented Programming will be in the 1980s what 
structured programming was in the 1970s. Everyone will be in favour of 
it. Every manufacturer will promote his products as supporting it. Every 
manager will pay lip service to it. Every programmer will practice it 
differently. And no one will just know what it is...

All parts should go together without forcing.  You must remember that
the parts you are reassembling were disassembled by you.  Therefore,
if you can't get them together again, there must be a reason.  By all
means, do not use a hammer.
