There was recently an accident near my house. Sadly it turned out to be fatal for one of the people involved. A lot of family & friends of the deceased have left flowers and messages by the site.
That was now some weeks ago and the flowers are, well, they've gone rotten and look shabby.
I'd like to tidy it, but, what's the soonest its acceptable to remove them?
straight after the funeral (whenever that is/was) ?
a month or two?
a year after it happened?
