Shit, shit, shit, guys. Feel free to take the piss out of me all you like, but I cocked up big and am officially the worst girlfriend ever. I completely forgot about Valentine's Day and I need the biggest favour in the world from you two. There's a little jewellery shop up the road from your store and I desperately need you to go in and buy me this ring for Sam. Please, please, please, you're the best brothers EVER.
