The fireworks were the best they had seen. This may have been partly as a result of the alcohol, no one was sure.
They were sure that it would be a great idea to shoot fireworks of their own off the roof however. The notion that this was a bad idea briefly danced upon the minds of most of the partygoers, but the alcohol cut in, leaving the notion a wallflower, alone and forgotten.
The first few fireworks flew flawlessly. The final few, not so much, careless laughter upset a stand.
The next thing anyone knew, the roof was burning.
