Chinese do not celebrate this holiday, so I didn't learn much about this holiday until I have lived in America for 2 or 3 years. Then, I haven't really participated a lot either, because I thought I am "too old" for this.
However, I was invited to an adult Halloween party a couple years ago, and there are many Halloween specialty stores in the malls that sell costumes for adults, too. So, I guess this holiday is not especially reserved for kids, after all.
The last time I went to the Halloween party, I sort of cheated. I just put on my husband's military uniform and dressed up like a sailor. I am not a very creative person, so I don't really have any brilliant ideas.
I am curious to know what or who you or your kids have dressed up as. Please share! :-)
