This is it. The dreaded day has arrived.Luke puts on his coat, picks up his schoolbag, kisses his mother and walks sadly out of the cosy nest that is his family home. The weather outside is horrible, very fitting for the first day back to school..."Good luck, darling!" he hears from the window.Luke does not turn round. He is afraid that the sight of his mother might drain all his energy and cause him to turn back... He doesn't want to go, but his mother has explained that it's not like when he was little. She can't make excuses for him forever, can she?The number 20 bus takes him in too short
