I am excited about this. I suppose this is some of what makes me Grammarissa... being (way too) excited about grammar and celebrating it.
I plan to have some festivities at my workplace, but I think the real fun will happen at home. Currently, Andy and I have been thinking about eating AlphaBits cereal and alphabet soup, running a slideshow of hilarious grammar mistakes, giving awards to our friends for good or bad grammar, and having a parade of grammar. We're not sure what a parade of grammar entails yet, but it could be excellent and that's what I'm working for. I want it to be an excellent celebration.
