I think we should all celebrate more often! In fact I propose that every year we celebrate the day you graduated - a sort of anniversary if you will - a birthday for your degree - well why not? You worked hard for it and it's important!
Make it a real tradition by getting yourself one of these sophisticated champagne flutes, (or better yet - get someone to buy you one as a gift) make sure you drink champagne from it on the big day, and then bring it out every year thereafter for the Gradiversary. Absolute genius!
This elegant piece of glassware is approximately 24cm tall, has the Durham University logo engraved on the side, and is a classic 'tulip' shape - designed to keep the bubbles where they're meant to be.
