Why do some people say “sleeping under the covers”?

They’re not covers, they’re BLANKETS.

And why do some people say “expresso” instead of “espresso”? There’s also a few people who don’t know the difference between poison and venom. Here’s the difference:

If you bite it and you die, it’s poisonous. If it bites you and you die, it’s venomous.

Would of, acks (yes, some people say that), using “text language” (lol, jk, idk, etc), supposebly, saying literally when they are figurative and mixing up their, they’re and there are some other examples of this.

Oh wait, I forgot people saying “a couple of X” when they mean 3-4 of X. A couple means 2!

Thank you for listening to my rant about misusing and misspelling words
