If he had used it as a verb, then you'd have room to bitch. That's the really offensive usage.

But to actually speak to the point of the post...

It does sometimes give me pause to re-read or listen to things and realize that my perspective has shifted, deepened and changed. I actually would rather stay where I am - if I was given the choice to go back to the end of high school. On the other hand, if that choice were offered with all the knowledge and perspective I have now, I might take it. Lessons learned and all that.
