Why is the keyword "virtual" a necessity?  It seems to me that C++ 
programs operate correctly without it (or maybe I just haven't been 
bitten by the beast yet).  The only place I routinely use the keyword 
"virtual" is in the header of destructors.  In shops where I've worked I 
have never seen "virtual" used at all.

Just wondering... what can't I do by not using "virtual"?  I can see the 
reasoning for "pure virtual", but "virtual"?
