I’ve spoken to a few people IRL about this and they seem to think I shouldn’t bother.
I always celebrate Halloween. And make it clear that trick or treaters are welcome to knock on my front door. However tomorrow, my DP is going out at 4pm and I won’t be in from work until 7:30pm. Would it be reasonable of me to put a sign up on my front door explaining this and that people are welcome to come after this time, or if they have younger children who may be in bed, that they are welcome to come on Wednesday night?
My dog will be in and barking most likely so I don’t want people thinking that I’m just avoiding answering the door :D
If you live in an area where people steal I am not sure putting a big sign on the house saying you are out is a good move. At best you may get some tricksters egging your house knowing you aren't in. At worst you will come home to find you have been burgled and as far as your insurance company is concerned you have advertised that your house in unoccupied.
We have cameras up and an alarm, and very good neighbours who are normally pottering about outside quite late anyway so I’m not too concerned about being burgled. I’ll leave a big bowl of sweets and keep some aside for people that might appear after 7.30! Thank you!
Just don't bother. No way would I be putting a sign on the door telling the world and it's dog that I was out! It's only Halloween trick or treaters, it's not the law that you have to answer. As for come on Weds - sorry to point out the obvious but that's not Halloween, is it.
Seriously, don't bother (unless you're trying to win the Lady Bountiful crown). Nobody is going to care less if you aren't there to hand out sweets for Halloween
Don't lumber your neighbour with the task of 'keeping an eye out'' for children at your door and giving them sweets. Apart from anything else he's going to look a bit dodgy rushing out to intercept children arriving at your house.
