Fri Oct 30 2015 19:49 Dress Up, Already: I think adults who don't dress up for Halloween are lame. You don't need to rent a full body costume. Put on some ears or get a t shirt. It's not that hard. And you can get something you can use every year. Even if you don't have kids, cool adults dress up. But it's particularly sad for adults to take really small kids trick or treating without any effort.
