How old is too old to go trick-or-treating? Chesapeake of Virginia says the answer to that question is anyone over the age of 12.

City officials recently announced that doorbell-ringing candy seekers over the age of 12 could face a charge, up to six months in jail, and $25 to $100 fines. They're far from alone. Meridian of Mississippi, Bishopville of South Carolina, and Boonsboro of Maryland, also have set the age at 12. The phenomenon isn't limited to the US: In 2017, Bathurst, a town in Canada, banned anyone older than 16.

Officials say they won't be actively looking to catch teenage trick-or-treaters in the act. The age limits are part of a broader push to limit pranks and tricks. Some parents think that preventing older kids from participating in Halloween traditions will have the opposite effect. A Facebook post last year argued that all kids, regardless of age, should be allowed to take part in trick-or-treating. It was shared more than 4,000 times, with close to 700 comments.

Some parents argued that kids shouldn't be spoiled. Others argued that even older kids should be encouraged to take part in it in the sense of wonder and excitement, and most said they were willing to give candy to whoever dressed up. That seems consistent with the scientific studies that play is essential to help children develop into healthy, well-adapted people, and that play encourages kids to develop collaboration and creativity.

Given how over-scheduled, anxious, and unhappy today's teens are, maybe a little Halloween magic is exactly in order.
