a tip on how to make it not-so-awkward when you're an adult trick-or-treating;
dress in whatever costume you like (duh)
go on with a group of kids or yourself
in a group; when somebody asks "aren't you a little old to be trick-or-treating" just say "i'm making sure they're safe and not getting into trouble"
alone; "oh i'm just making sure everyone's safe and stuff" or something like that
