My Weird Brain

Yes, I know, that's a shocker. My brain really is weird. Anyways, here's the reason why:
I was reading over the passage for Bible Study tonight and for some strange reason started thinking about the word "again." Again. Again...a-gain. "A" is a prefix in the English language meaning without. Gain, of course, is to aquire something new. So, "again" would be without gain! Think about it...if you're saying something "again," you're not really adding any knowledge to anyone, because they already all know it! Of course, this theory isn't perfect, but I thought it was interesting.
Yup, that's just the way my head works.
