(Halloween thread in Misc, which I don't think she'll mind my quoting)
But I'm one of those "miserable scrote mothers", who thinks it's rude to knock and ask for lollies to strangers.
Fair enough if it's all set up and arranged beforehand and all the target neighbours have been warned and even supplied with lollies to give - but otherwise I think it's just not on to knock and ask for stuff.
Don't really like them stuffing their faces with kilos of cheap coloured sugar either.
Costume party fine, but not door knocking.
What are the "tricks" going to be anyway??
