Sore throat

Roger has taken a bite of his sandwich, chews the piece of breakfast that he has in his mouth and, when he has it well crushed, he swallows it. How it hurts! What on earth has gone down his throat? Roger looks at his sandwich. No, he hasn’t got confused and is eating a ‘fakir’s breakfast’; it is just bread with cheese.

Roger has a sore throat. Finishing this sandwich today will be as hard as climbing the highest mountain in the world wearing flip-flops.
