Ahhh, this is a sad one. Until very recently, Grumpy Cat was the face of all of us who were being made to do something we didn't want to do. Those early mornings when we woke up and didn't want to go to work or school, those awkward social engagements that we just knew were going to be a disaster, and our general sense of malaise with the world around us were all best summed up by the permanently-dour face of Grumpy Cat.
Sadly, Grumpy Cat passed away a little earlier in 2019. She was never truly all that grumpy - she just had feline dwarfism coupled with an overbite that made her look like she was frowning all the time. She and her human made a fortune from her likeness over the years, and she lived as happy and comfortable a life as any cat could wish for. She was still pulling her famous face right to the end.
