See, I think it would be more boring if people decided to celebrate Christmas at all times of year. Surely it's nicer and more exciting if everyone comes together to celebrate?
come together and celebrate christmas at christmas time for sure if that makes it special and exciting for you but why does it stop being nicer and more exciting for you because someone wanted to put their lights up a bit early to make it nicer and exciting for them a bit earlier?? no ones talking about celebrating christmas at all times of the year though, we're talking about putting the decorations up.
if it cheers someone up to bung their lights and tree up in October why should anyone else get knicker twisted over that (i'm not suggesting you personally are - my post was more aimed at those who do)
why does the op feel he needs to ask when is it ok to put up their decorations? it should be ok whenever they want to.
wanna put them up in July? have at it, it'll make the person putting them up happy and it'll for sure give plenty of others a laugh and the only ones to not get any pleasure out of it will be the perennially annoyed curtain twitchers, who lets be honest, don't matter a ****.
