People Who Don’t Use Simple Punctuation

I am not trying to be a grammer natzi because in texts and emails to friends i dont really care. But i cant stand when people dont use simple punctuation like periods. I read a post and there wasn’t a single period, comma, or anything in the entire post. It looked like the entire four line post was one sentence and i couldn’t read it with out stopping and figuring it out. it’s really not that hard!
