Strange Thoughts of a Strange Man

I have just finished the course I have been giving. I've dished out the certificates, given out the evaluation forms and got them back, I've taken my computer back upstairs to my office and handed a copy of the notes to a new colleague who wanted to come on the course but didn't have time.

I've sort of come off a bit of a high now and feel a bit estranged from reality. it's like I'm on my own little planet.

I've been preparing for this course for weeks and the past two and a half days have been very intense, very rewarding and very tiring.

What on earth do I do now?
