Yes, I know that Ann Taylor is having a huge sale, but I'm going to have a memorable day with my family at the races. Kids grow up way too fast, and it's important to spend quality time together.

They'll be so engrossed in the race, they'll never know ... until my packages arrive. I'll have to explain THAT later, but that's DAYS away.
