There are definitely too many to pick just one. Going to India, Abu Dhabi and South Africa in my first three years for cricket tour was unforgettable. Also the novelty of walking up the steps at main building never wore off.
But my favourite memory from my time at Malvern was the relationship I formed with my boarding house. You get to know your boarding house mates on a deeper level than normal when you're living with them and sharing so many experiences with them. You become emotionally attached to your house and the people that both live and work within it and it truly feels like one big extended family. A particular memory that stands out is Christmas Supper, each year. After a long and very tiring first term, Christmas celebrations the evening before everyone broke up for the holidays made you feel like you wanted to stay at the school throughout the rest of December.
