You wait until the friend gets the balls to ask for the cord after you avoid the blue blazes out of her, then you say “OOooHhhh YYyyEeah!!!? Riiiiiiight the coooooord, I’ll get that to you first thing!” That bought you like two days maximum. Buy both Cords while you are waiting on the friend to get the nerve up to demand the cord back. Save the receipts, and make sure you get them from a place with a super liberal return policy. Carefully open the expensive model, and have it somewhere safe and handy where you won’t lose it again that looks natural in case the friend shows up wild eyed. Now hope and pray that they drop that ipod, or get in some sort of fiscal jam that will entail getting rid of that Ipod.
You might call the copyright police on them to get that Ipod confiscated to… They might just be thievish hoodlum like you. Birds of a flea lay down together.
