I'm sitting here watching my kid Ben who is three.
He has a new Thomas the tank train track, wee battery op thing.
Anyway it has this tunnel and each time it went through it the carriage was getting stuck on the tunnel wall.
I watched with great interest to see how he was going to solve the problem and if not to see how long he would persevere before asking me to fix it.
After around 20 seconds he lifted the tunnel clean off and discarded it to the side.
I thought to myself 'clever boy, if you can't fix the problem then remove the problem'
