My dad's birthday is on Hallowe'en, and I always went there - it also Samhain, and as we are Pagans we'd have our ritual & celebration too.
I used to return home to find my house egged, and twice windows broken - to those who think that I therefore now refuse to participate - due to the vandalism I now associate with it - makes me in some way 'miserable' I'd respectfully point out that you are off your rockers!
When I reported the eggs incident to the police (it was on all my windows, my door & worse the brickwork - which proved impossible to remove. The police gave me a poster to use the following year - one of the times that the windows were smashed.
Of course it wasn't young kids who were responsible, but the same scum that did this also did it to elderly people - who would never know whether a knocker was a young child having fun, or an abusive, blackmailing, anti-social teen.
I also don't want to take part, as for me it has a strong religious aspect which has been used to exploit by some, and as another commercial enterprise by big companies.
