AN EXCERSISE IN...?

OBSERVATION! Don't panic, this blog is not going to turn into pics of moi only (although im sure kat and justin would not be surprised if it did!), this is merley an experiment in the suptilties (spelling please?) of expression!
Note:
first pic taken fri 7.30am: Happy but not thrilled, like going to work b/c have exciting job, but am STILL ON WAY TO WORK!

second pic taken at 5pm: Hello weekend!

Can you spot the difference!
