Walburga hurried him out of the door with just a juice box and a note, pointing rather vaguely at the house opposite them. “Go! Go over there. Give this to whoever answers, quickly.” She told him as she continued shooing him, up until the point where she was able to slam the door in his face. Regulus simply gave the closed door a quick look of bemusement.
He was confused about the entire situation, if he was being perfectly honest. They’d moved house so quickly, Regulus wasn’t even fully convinced this wasn’t an impromptu holiday. If it weren’t for the stress of his parents, of course, who had been snapping at him more than usual. And the continuation of burnt food that Orion continued to give him and his brother without any sort of finesse, calling them ungrateful when they couldn’t finish due to its lack of edibility.
Regulus hopped across the road without looking which earned a yell behind him. He turned to see his brother and his brothers best friend (bane of Regulus’ existence) push off from their bikes. “Look right and left, Reggie!” Sirius demanded. Regulus ignored him and continued on his way, making it to the other side of the road unharmed.
He approached the door and knocked twice, waiting patiently until the door opened to someone unfamiliar. Regulus handed the note to the adult who answered the door without a word, opting to take another large slurp of his juice box.
We are the family who have moved in across the road. We cannot greet you personally.
This is our youngest son, Regulus. He is eight. We notice you have children. Perhaps they can be acquainted, it would be useful.
He glanced over his shoulder in time to see Sirius and James cycling away – the former giving an enthusiastic wave as he passed. Regulus waved back less enthusiastically before turning back and blinking up at the adult, as if waiting for instruction. He was never good with meeting strangers.
