Oops!

(This has nothing to do with teaching or counseling, but is an example of a mistake I made as a STUDENT!)  

I went to a computer class at the Apple Store today, and the trainer asked me to type a word on a slide just to show her that I understood up to that point. I sincerely thought I typed "Hello!", so I grinned at her with a sense of accomplishment. Noticing her shocked expression, I looked at the computer and saw that I had typed "Hell!" Was my face red!
