I think you should go trick-or-treating this year. After all, a big part of costumes and trick-or-treating is wearing masks, so if people wear fun ones that match their costumes that will give them protection when they are collecting their candy. If your mask is too much at some point you can go to an isolated area and take a mask break, then join with your family again and continue.  When you are not collecting your candy you are walking around. While you are doing this you can stay away from other people and only be around people who you are comfortable with. If people do that then everyone would be at a safe distance. After all, COVID-19 is spread by people not wearing masks or not social distancing so if you do those things it will not spread easily.

Once you are done trick-or-treating you can either sanitize your candy, let it sit untouched for two weeks, or throw away/give away what candy you do not like and sanitize the rest. For some families that have younger children sometimes all the fun is getting dressed up, walking around with your friends and getting to see other costumes. In that case and many others,  the candy just sits in a bin for months then gets thrown away next Easter. So, if you are not going to eat the candy you should consider donating it to organizations. Some collect candy to give to military and first responders. An organization called Operation Gratitude is doing a Halloween candy give back program where you can donate and candy you will not eat or do not need. 

If you choose to not wear a mask, not social distance, or even if you are unsure if you have any germs, you should consider quarantining from other people for around two weeks. At two weeks after exposure is when you begin to show symptoms of COVID-19. So, if you do not have symptoms you most likely do not have the virus. That way you can not give it to other people and you can be sure whether or not you have COVID-19. 

This is why I think you should go trick-or-treating this year!
