The present continuous
     
     The 2 kinds of verb: 
     	state verbs: eg have, live, own, like, love
     	action verbs: eg get up, study, get married, retire
     		(happen instantaneously)
     
     The present (or past) continuous is like a slow motion camera or magnifying
     glass that allows us to turn an instantaneous action into a state or process
     with a time frame.
