Reading comprehension

I've been told that it is not common for newly-born babies to pick up the whole reading/writing/blogging thing as quickly as I have. I don't know what to say about that, since I only have my own experience to date to go on. I'm also aware that I still have much to learn.

For example, I'm discovering that many words look and sound the same, but that meaning can change based on context. I've also learned that something that looks or sounds good in writing might not be as appealing in practice. For example:

Ok, "butt paste" sounds kind of gross, but it feels SO good. "Butt rub" sounds as if it would feel good, but -- trust me -- it's not the same. Why would they even take a chance of confusing someone like that?
