No poo in class thank you

What is it with men and their fascination with bodily functions and secretions? I hate to generalise but i'm talking about men in their early twenties acting like teenagers. I taught a class of young ESL students today and a group of four young men spent a good hour or more chatting away about their bodily functions!

Ah but they were speaking in English and therefore studying you say? Nope. Each time I set a pair/group discussion task, off they would go again talking about their poo in their own language.

Aaarrgghhh. How gross! They are adults! They have spent a whole heap of money to be here studying English! They are surrounded by students of other nationalities. Perfect opportunity to make new friends, learn a new lanaguage and expand your possibilities.

They choose poo. Good choice boys.
