None of us had dressed for Halloween for years, and we were concerned that our age might provoke a negative reaction. (We ventured far from our college, into residential areas used to trick-or-treaters less than half our age.) What we discovered instead were warm smiles, generous people, and an interesting sort of mixed interaction. While we were partly perceived as trick-or-treaters -- and thus categorized as 'children' -- we were also perceived as adults, and received the 'above-their-heads' knowing smiles and nods given to the parents shepherding their tiny masked ghouls, tigers and fairies around.
