The evolution of laughter

At some point in the last decade, haha became ha. It was strange - suddenly people had shortened the act of laughing in pinged lingo.
It was a punchier laugh. HA! It struck you as being truly funny, almost violently funny.
Haha was frowned upon, like coming in to work wearing one black shoe and one yellow shoe.
So there I was laughing at everything with a ha. It was easy enough to write.
Then I was horrified to see haha sneaking back in to chats, like a 50s dance tribute.
It confused me — language had evolved yet again. I could now switch between haha and ha depending on how hard or how long I was laughing.
God forbid I actually laughed for a sustained period of time, I may even add some more ha to the end like this: hahaha.
A friend of mine introduced the concept of ahaha to me. It blew my mind.
I guess all laughing is equally valid. That’s the sort of world we live in now. Whether you’re hahaing or haing, it really doesn’t matter as long as you’re laughing. Ha.
