Trick or Treating Age Question

I was just texting my best friend when she asked me what I'd be doing for Halloween night. Since it is usually snowing or raining on Halloween night and considering my condition, I told her that I would probably just be watching horror movies all night. She told me that a bunch of our old friends (friends that I don't consider as friends now) are going to go out trick or treating and she turned them down. The group of friends that are going out that night to ask for candy are older than me, being ages between 22-26.

I thought that was way too old and they should grow up and start to celebrate Halloween the way adults do (going to parties, going to a haunted house, going to horror movies, etc) and leave the begging for treats for the kids.

I don't have a problem with trick or treating when kids are in high school. I don't care if they do it when they're 19 but I think that when you are thru with your teen years, that you should leave the kids to celebrate their Halloween.

So what do you guys think is the appropriate age to not trick or treat anymore? Do you think the group of friends are being immature? Or do you not mind them?

Happy Halloween! :evil:
