Capitalization of names is useful.

The left should've had "Jack" capitalized to insinuate that it was a person's name; followed by a comma, distinguishing what's the verb, and noun to the sentence.

My overthinking has given me a headache.

I was going to do this, but then realized the lack of punctuation and capitalization portrays the idea that the same exact sentence can mean two separate things.

I get what you're trying to say, but this meme conveys that you're having 2 reactions to jacking a horse off, not emphasising the difference from capitalisation.

Comma placement, very important.

I read them the first one the way the second one was supposed to be read
