While Mrs M watches the world's worst reality TV show I find myself puzzled. How can it be that some men can be so singularly stupid about such obvious things?

Over the last few months I have heard of several men who have been caught having affairs. Nothing unusual about that. However every single one of them has been discovered through their mobile phones. A text message undeleted; a called dialled to an unknown number. Women don't become stupid when they become wives. Quite the opposite. However some men seem to actually drop IQs once the wedding ring slips onto their finger.

I am a faithful man. But really if any of these men had put in two seconds thought they would have availed themselves of one of two simple solutions. Either wipe your messages and dialled numbers when you get home, or have a seperate phone/SIM card. Not difficult and not expensive. While I do not condone such affairs it seems so immensely stupid to be discovered this way.

Unless they want to get caught.
