Gee don't we all kind of want to turn our house/yards into a Disneyland Haunted Mansion setting of sorts if we could? I like her house and think it's very tastefully decorated. I'm not particularly into the dog thing but lots of kids and their parents probably enjoy it. Definitely not totally my style but still like it. Doesn't look like she needs to build gates for her house (a bit too ornate for me) but having real gates to work with is totally cool in my book.
Personally the fact that she decorates at all and makes it fun for the kids on top of it is pretty neat and handing out candy in costume...well I wish my parents would have exhibited some of that getting into the spirit more.
I kind of feel like you're objecting to what she is doing somehow and just not sure if you are bothered by the decorating, dogs, her dressing up as a princess, the fact she has a nice lifestyle or her handing out money, but the post kind of leaves me feeling that way. She could just as easily lock her gates and turn away Trick or Treaters.
