Halloween in the US is a pretty big deal, dating all the way back before WWII. Just about everyone today who will be yelling "trick-or-treat" will do so with a flimsy plastic pumpkin in hand, secured by last year's duct tape and a whole lot of hope. But this year you may notice something different about the delicacy depositories.

Some candy containers will have the same familiar grin, matched by the gal or ghoul holding it, but some are blue. Turns out, there is a very important message these containers are trying to convey. It means the child with the bucket may not be able or comfortable saying "trick or treat" when approaching your house.

The trend caught steam (138k shares) after a mother of a 3 year old posted an image of a blue pumpkin bucket to Facebook stating:

"My son is 3 years old and has autism. He is nonverbal. Last year houses will wait for him to say TRICK OR TREAT in order for him to get a piece of candy and there I go explaining the situation for the next 5 blocks. This year we will be trying the BLUE BUCKET to signify he has autism. Please allow him(or anyone with a BLUE BUCKET) to enjoy this day and don't worry I'll still say TRICK OR TREAT for him" -via Facebook

Some houses have pumpkins on the porch that are painted blue to signal the same message. Be courteous, be kind. After all, Halloween is a wonderful time where kids can be whatever they want for just a few short hours. While some want to be a police officer, a princess or a fortnight character, others want to just be respected. Let's do our best this season to be on the lookout and spread the word!
