Join the dots

I don't think I have mentioned that lately I have been lecturing a couple of days a week. I love teaching and my students are wonderful. I have found though that I have developed little habits when I speak in front of the class. For example, if I am holding a whiteboard marker I will at times press the lidded pen against me without realising it.

Well today I didn't realise that the lid was off and this is what happened.



I have been walking around for the best part of the day with a 'join the dots' pattern on my stomach. Sigh.

It is almost the weekend.
