Albert unlocked the thin wooden door of the old shed - more of a shack really - and retrieved the relic of a lawnmower from the darkness. The light bulb had blown, he had better get a new one next time he was in town. He glanced up at the sky above. The fat grey clouds promised rain so he had better start quickly. As he began to cut the grass of the little graveyard, he noticed a man enter through the gates with a large, black dog at his side. Albert shrugged - it wasn't any of his business - and started up the green lawnmower. With a rattling roar, the lawnmower struggled into life.
He looked up again at the man and his dog - he wasn't nosy, mind, just a little inquisitive - and saw with surprise that the dog was gone. Instead another man stood there, dressed in clothes of a distinctly better quality than the first man. As Albert watched, the well-dressed man sank to his knees before the grave, and buried his face in his hands. Albert sighed. He remembered that funeral, though it had been a while ago now. A huge number of quite oddly dressed people had turned up, all seemingly heart-broken. A young couple it'd been. What were their names? Something beginning with P, Albert thought.
As he passed closer to the grave, Albert caught a glimpse of the man on his knees. He had the air of a young man who'd seen far too much for his years. The other man looked at his companion with terrible sadness. Albert shook his head and continued on in his work. He could feel a few droplets of rain landing on his face and grimaced. He'd have to leave this for a better day, he decided. He completed one circuit of the graveyard before returning the lawnmower to the dilapidated shed in the corner.
As soon as he'd locked the door, the heavens opened. Albert shrugged his coat over his head, regretting not taking the anorak with him as his wife had advised. He half-ran, half-limped down the path, passing the two men on his way who hadn't moved an inch despite the torrential rain. Albert approached one of them hesitantly.
'Are you planning on staying here much longer?'
The one standing turned round in surprise, hand reaching, seemingly involuntarily, for his pocket. As he saw Albert however, he smiled slightly. 'A bit longer maybe, I think. Is that ok?'
Albert nodded. These men made him nervous for some reason. 'That's fine. Just mind you close the gate behind you on the way out.'
'Of course,' the man said warmly and then turned back to the grave stone.
Albert stood there for a moment later before shaking himself and turning to leave. As he shut the gate on his way out, he noticed the two men in a tight embrace, the well-dressed man seemed to be crying though it may have been the rain.
Potters. That's who were buried there, Albert remembered as he left.
AN: Albert is just an old, Muggle OC. The two men are Sirius and Remus (Sirius is the well-dressed one). Hope you liked it, please leave a review!
