Happy festive emotions?!

A long time ago, I wrote about emotions and emojifying your life.  As many of you know, I’m not overly keen on emojis and the little icons that are consuming our virtual reality, because, it seems to me, that you need a degree in neuroscience to work out what they all mean. Truthfully, the only ones I completely understand are the dancing disco man, the octopus, the tractor, and the erupting volcano. However, I´m completely unsure as to when these would be useful! Seriously, you tell me!

So, thankfully, instead of ridiculing me and mocking me, a friend of mine has sent me a cheat sheet to help me decode these little smiley, grumpy, happy, confused looking faces.  But, what does this mean?
