I wasn't sure where else to post this so I chose here 

  Anyway, a few months ago several of my friends said I should have a birthday party this year.  I'll be turning 17 at the end of November.  Is 17 too old to have a party?  And if I did my party a few weeks early (beginning-mid November), would a Halloween themed party be a good idea?  I was thinking have everyone wear their costumes (yes, we all still dress up for Halloween 

 ), having a bunch of cool Halloween food, and just have fun hanging out, maybe playing a few group games if people want to.  What do you guys think?
**Also, part of why I want to do this is because last year I felt like one of my friends had the party instead of me because ti wasn't really what I wanted to do.  I just didn't have any better ideas since it was kind of last minute.
