One Sketch #23) Classroom door

As I said in yesterday's post, this is my first week back in work - school - since the Easter break. It's been a hard day. Part of my problem is that the older you get, the less tolerant you get, and the harder it is to put up with the niggling little darlings.

I am too old
A fossil from the chalk age
Too old to do something else
And too young to finish.

Gosh, that's miserable isn't it. Sorry, it's been that kind of day.
