It's a thing of 2 parts for me;
1. We dress up and go to our grandsons house in our village, where DD and SIL also dress up. We have a lovely special tea , and then DGS does a bit of trick or treating with SIL, then DGS loves answering the door and handing out sweets to the children who come [lots of them come.]We play a few games and play Ghostbusters music and are generally silly. We like seeing the little ones dressed up [aww, one tiny tot was a pumpkin.]Anyone who puts out a pumpkin or any Halloween stuff in the drive is inviting children to knock on the door, for those houses who don't, callers stay away.That's all great.
2. Not so great......! The supermarkets who stock the most horrific things for Halloween just where toddlers are walking past. I have seen several crying, and no wonder, severed hands and feet [way too realistic] and blood spattered swords and axes etc. on sale, grotesque masks too.
