What do you think about the book 1 and book 7 Snape parallels?

Here are two cool ones I found. If you have anymore post them here!

#1 The first encounter and last encounter we have with Snape is him looking in Harry's eyes. (Book one the first time we meet Snape he's looking past quirrels turban in to Harry's eyes, and the last time we meet Snape, he is asking Harry to look in his eyes)

#2 Throughout all of Book 1 Harry thinks that Snape is bad (until Quirrel tells us he's not) Throughout all of Book 7 Harry thinks Snape's bad. (until snape's memories tell us otherwise)
