Is it very mean of me...

To insist we don't watch the final episode of Blake's 7 (on the DVD set) until 21st Decmber?

I favour waiting; Looby Loo, who's watching for the first time, can't wait. (She may persaude me to give in by worrying about what's going to happen to Avon. I could cause a long postponement by giving her the boxed set of Harry Potter movies on Saturday.)

 It's mean, right? But, they're my DVDs.
