Possible to be retarded one day and normal the next?

That's a ridiculous and totally inaccurate use of the term "retarded", or the word "literally", unless you are in fact actually intellectually backward?

You weren't forming your thoughts to well when you wrote this post, were you?

Your use of the word retarded triggered me and set off my PTSD.

Is "retarded" still an acceptable term in the USA?

As for what you experienced, I think the person who suggested an allergic reaction might have a good point. If your eyes are puffy, your sinuses are clogged up, and you're feeling vaguely generally crap, it can be difficult to think clearly.

Lol.

Well, you shouldn't say retarded, because that is gonna piss off a lot of people, and truthfully you aren't diagnosed as retarded.

However, it is possible that you may have problems concentrating, and find yourself feeling very out of it due to your sinuses. It's possible that you may have a sinus infection. I used to get lots of chronic sinus infections when I lived in Las Vegas, because I have a hard time with a really dry air especially during allergy season.

what i think at school everyday

No, I don't think you can be that one day.
We all have off days though.
As for the word retarded.
I guess I follow:
George Carlin, or
Carlos Mencia.
It's not offensive, it's descriptive.
It's a medical condition.
No judgement, it could have happened to any of us.
What's not so understandable is when people with full functionality and control.
Do stupid things that even a retard would know better about.

PFFFT LMAO you don't get "retarded" from alergys!

Guys. Most people use the word “Retarded” just to get a rise out of people. If you don’t give the word any power, it won’t have any power over you.
