That 'everybody else in the world!' had? For me it was a tamagotchi. My mum was afraid of it waking me up at night because she heard you couldn't switch them off. I desperately wanted a 101 dalmatians one. I have a lump in my throat thinking about it now! It felt so lonely to be the only one in the playground without one. I even looped a Christmas cracker keyring over my finger and held it in my hand so I could pretend to myself I was like the others. 
What about you guys?
