Mints.
Smints, to be precise. The blue ones, but i'll take the green ones in a desperate situation.
For some reason I really hate gum - I hate chewing it once it gets past the flavoursome stage. And then I hate seeing other people chewing it with their mouths open. And then I hate seeing it (or worse, inadvertently
touching it) stuck everywhere. And I really, really,
really hate it when people click little bubbles in their gum. Over and over and over again. Especially behind you on a bus.
No offence to anyone who does eat gum, though, I'm sure you're all very responsible.
Oh, and I was surprised to see in devilot's "Altoid" thread, that they say "Made in England" on them. I've never seen them here. I'd always assumed they were American. Either I'm blind (which is possible), or they're one of those things that is technically British but is impossible to get hold of here. I'm on a mission now to find some....
