This is because my mom is scheduled for surgery next week. (Don't worry, it's nothing life-threatening.) There's still one more chance for those darn surgeons to say "No wait, let's postpone it again", and the surgery to end up happening just before Megaplex and forcing me to cancel my trip... but that's not very likely.
And boy am I glad! Because although I love my mom and I want to help her recover from the operation and be there for her... I'm also looking forward to visiting Florida and getting away from this miserable weather!
