Am I Too Old To Trick or Treat?

My mommy thinks im too old to go Trick or Treating. I love to Trick or Treat! I look forward to it every year, and i take my 11 year old sister with a friend or two usually so i don't look completely ridiculous. The thing is, i'm really excited to go because it is one of the very few days a year where i can be as silly as i want without being chastized. Plus i already have my costume! I'm going to be a fairy! I have a neon yellow tutu, neon blue wings, and accesories! Well do you think i should go Trick or Treating or is 15 years old too big a number? Comment!
