I've heard of Irritable Bowel Syndrome, but I am now witnessing Lazy Bowel Syndrome in action.
Whenever we ask Teenager to do something, the response is, "I've got to go to the toilet!"
"Clean you room".
"I need to crap!"
"Hang up your clothes"
"Mow the lawn"
"I need to go - right now!"
He then hangs around in the toilet until he thinks the coast is clear - ie, we have forgotten about the task at hand. Unfortunately for him, we cottoned onto this behaviour some time ago, and we just hang around chuckling at him until he emerges - and then he's put back on task.
The hilarious thing is that he thinks he's getting away with it.
