34 Cents
Fun fact: I keep postcard stamps with me at all times.
Well, they don’t come with me when I’m brushing my teeth or anything, but when I’m out and about in the world, they are always with me.
The way I see it, there aren’t many things left in the world that cost 34 cents and have the potential to bring that much levity to someone’s day. Are there other things? None are coming to mind at the moment.
