Magpie:
But she still seems to be being asked if people ever *do* magic for 
the first time as adults rather than as children, which indicates 
the person is asking about either Squibs or Muggles--non magical 
people finding out they can do magic.  She says "find out their 
magic potential" but it seems to be referring to their ability to do 
magic, not how good a wizard they will be.  She says someone 
will "in desperate circumstances do magic quite late in life," but 
Neville's been doing magic regularly for six years, starting out the 
regular age. He could certainly do something impressive at this 
point, but that wouldn't make him one of these rare people as far as 
I can see--he's already gotten an EE in DADA, which indicates to me 
he's pretty adept. I think we're supposed to take McGonagall's word 
for it when she says his biggest problem is lack of confidence.  He 
doesn't need desperate circumstances to do magic.
