    Transfiguration with Professor McGonagall was exciting, if challenging. In their first lesson, she transformed her desk into a pig and then back again. The Slytherins were impressed, but held back any form of excitement – except for Ron. He was practically wriggling in his seat, ready to get started, and Harry had to hold back a laugh at the look on his face when Professor McGonagall began writing notes on the board for them to copy down. After they’d completed the notes, they were all given a match and started trying to turn it into a needle. Harry hadn’t expected to be able to do it straight away, but others evidently had. Harry heard several Slytherins cursing at their match angrily.
