This is Like a Blog Post

I remember in 4th grade, my teacher, Mrs. Plantinga, had a summary opposition to, like, the work "like." She tried to convince us not to use it every other word; however, in the early '90's, everyone was, like, doing it, especially all the cool kids, so we just brushed her off. I still find myself using it; however, I never actually used it in writing.

Now that I'm a teacher myself, I'm finding that I have the same opposition to the word. On my most recent book sign-up sheets, I got things like the following:

"It has like no back cover."
"It's like destroyed."

On a recent freshman test:
"A narrative paragraph is where a narrator is like telling a story." (No, the narrator IS telling a story.)

In class this morning:
"Are we going to, like, read, like, a book in this class?" (No. We're going to read a book. Although perhaps "like reading" is a better description of what some of my students actually do.)

I realize that it's really just a filler - rather than "um" or "uh", people say "like." I do it myself.

But am I, like, really subject to this in, like, writing too?
