Now I'm embarrassed

Someone's just come in to ask me to turn down my swearing because students are doing an exam. I'm normally very mild-mannered, but PebblePad is turning me into a dishevelled wild-eyed monster. I've had to turn up Tosca to drown out my Tourettish cursing. I could actually have finished the outstanding piece of work, were it not for the 4 hours it's taken so far to upload a few documents. It shouldn't take 5 goes to highlight a piece of text or add a link.

I've also sent an angry letter to the PGCE people.
