Grammatical Errors

Spelling and grammar have always been something that has bugged me. I have always found myself to be quite good at spelling, and take care to make sure what I am writing actually makes sense and the punctuation is correct.
I am ashamed to say that several years ago when I was a young teen, I conformed to the craze of writing incorrectly.
I am ashamed and so embarrassed of how I used to write/type informally to my friends.
This is how it looked..

‘hEy hOw arE yOuu tOdAy??
iMm gOinG oUt lAtEr iF yOuu wAnT tO cOmE?’

*Facepalm*
Why oh why did my generation including myself used to type like this?
It shows nothing but stupidity and a lack of general English skills.
I can’t even look back and laugh as it is so embarrassing that I was a part of this madness.
That is literally how we would all speak to each other, including hundreds of other young people.
It didn’t make any sense. You would randomly change a letter in a word to a capital for no reason whatsoever. The only letter that would always stay small is the ‘i’. I don’t know why this was; I guess we thought it looked better staying small.
Adding extra letters to a word, such as one or two extra vowels, to ‘exaggerate’ the word.
And you can imagine how time consuming it was. A simple sentence would take triple the time to type, due to the constant changing from caps lock back to non capitals.
It is something that most young people did from the age of 12-15 in my generation. That is until we suddenly wondered what on earth we was doing.

I guess we all have done things that we look back on and just shake our heads.
