I want to say :
It is okay to have fun at new year's eve ,however think about others.
The only part that I was able to translate is :
おしょうがつにたのしみますだいじょうぶでも.....
and I can't complete.
The situation is that people at new year's eve throw their old stuff,beer bottles,garbage,etc.. in the streets. The next day it becomes very hard for the street cleaners to clean that mess so it is kind of sad. I want to write that it is okay to have fun at that day however be considerate to others.
