I am so glad Halloween is in half term and we're away this year.
I hate the masses of children bordering on youths who come knocking at the door with one shop bought mask between them. [hangry]
I hate the whole begging dressed up as 'trick or treating' to be honest [hblush]
I hate the whole commercial aspect, supermarkets cashing in on loads of confectionary, dressing up stuff etc
I hate the guilt trip. We're a Christian family (Army bit in nickname is The Salvation Army) but I've always taken the "It's just a bit of fun" rather than "celebrating evil" line. Which is right I'm not sure (views please) but I never want to deprive DC of some 'harmless' fun. 
I do love smileys tho' and have no qualms about using the halloween ones [hsmile]
