A few starting notes:
I thought that I didn't know anything about 'Sarah's Scribbles' - but then I started to read Adulthood is a Myth (UK - USA), and realised I had seen so many of these cartoons before!
I guarantee that if you spend much time on Pinterest, Tumblr, or Facebook, you will have seen more than a few of these cartoons - and laughed. I'm pretty sure you'll laugh even harder on the re-reading.
The drawing style is cute and slightly derpy in that internet-y meme-ish way (that sentence was close to English... but I'm not entirely sure it counts.) It's endearing, but manages to avoid creeping into the 'annoying' zone.
