I have been in a play for the past few weeks (I have a small part so I haven't had to be there the whole time) and opening weekend was this weekend. Tonight is Halloween and it's our closing performance, and I'm actually really sad im missing out. I was invited to 3 different parties this weekend and didnt go to any of them because of the play. I know it's my own fault for trying out for the play, but I'm just wondering if it would be acceptable to celebrate Halloween after the 31st since I missed out.
