not an expert in hand writing but "you" seems to be written a bit different :?

what boders me most with this note is the fact, that in the original post Nelson said that the note said "Thanks-Michael":
# Came back from trip to find mysterious box at door-filled with: Michael Jackson London tour items (t-shirts, wine glass, wallet, cap) more.. 8:19 PM Sep 1st from web
# ..cont'd..All it said was on box was, "Thanks- Michael" Must be from a fan of both mine & Michael's-I have no idea-anyone?? 8:22 PM Sep 1st from web
Then, I think after he got some questions on the note (from some of us here I guess ;) ), the note seemed to change into "Thank you!"
So, couple of questions here:
- was the note originally "Thank you" only - but then why he added "Michael" in first place?
- was the note originally "Thanks-Michael" - and only after he got questions on the note, he realized what it may mean? and change it by himself or someone told him to change it :? :? :?
