[HPforGrownups] Handwriting example of what I mean

I realized after my last post that I actually can point you all at an 
example of handwriting over time. You can see from this persons post 
that they unearthed samples of handwriting over an extensive period of 
time. Now, between 17 and adulthood there is not a huge difference, but 
I don't know that I would know it is the same writing or connect it 
unless I was specifically looking for a connection. Just thought it 
would be interesting for  people to see one example.

(and as you can see from the forum, there *are* a lot of people who 
work and continue to work at changing their writing. Snape doesn't 
strike me as a pen nut, BUT there is no doubt he has worked on self 
esteem and image from when he was 16. It isn't unfathomable that 
handwriting might shift because of that alone.)
