My soccer coach retired in last week．I wanted to do anything special for him at his retirement party．My mum makes the better biscuits in the world，so I decide to ask her for help．Mum taught me some basic step of baking．I insisted on doing most of the baking myself. I thought the biscuits were really well．My only mistake was that I dropped some on the floor after I was packing them up．
At a party, my coach, with a biscuit in his mouth, asked surprisingly who made them and joked, "I might have to retire again next year just get some more of these biscuits.”
My favorite picture at the party is of my coach and me enjoy the biscuits with happy laughter!
