Once again Aidan found himself in a hurry as he took the last corner that separated him from Terry's flat at a run. Having spent most of his time among Muggles the Irishman still preferred walking (or running in this case) to Apparition, Floo-ing or - he shuddered at the mere thought - flying.
Upon arrival Aidan came to an abrupt halt in front of Terry's door and - instead of using the doorbell like any sane person would - opted to knock against the wood of the door with the bottle he brought.
"Come on, mate! Open up!" Aidan yelled. "I brought drinks!" That should do the trick.
