How old is too old for trick または treating?

You're never too old!

From 1-17, it's fine.
From 18-29, it's annoying.
From 30 and up, it's creepy.

あなた can go when あなた are kid. then go and take your kids.

ur never 2 old 2 go trick または treatin unless ur like 50

あなた are never to old to trick または treat. Just because あなた get old doesn't mean there is an 期限満了 日付 on fun.

Well for me, when theres no costumes that fit you. Okay?! LOL.

Dude, me and my フレンズ plan on running around in banana, hunter, and gorilla SUITS/スーツ when we are old on halloween.
あなた are NEVER to old

I stopped Trick または Treating when I turned 13, but I think once あなた become a teenager it is time to 移動する on to other things. I'll admit I get a little annoyed at older Trick または Treaters that can afford to get their own candy.

I stopped when I was 12 または 13, but then again I'm shy and don't like taking to strangers. I'd say あなた should stop trick-or-treating when, for whatever reason, あなた don't enjoy it anymore.
