Once, I bought a pair of shoes that were a size too small, figuring that somehow, one day, I will fit into them. But they will never fit because there are some things in life you can never change. As much as you try and convince yourself you can, all you end up doing is lying to yourself.
Perhaps when you wear those shoes enough, they get easier to wear with time.
But is it worth it, to put yourself through excruciating pain?
It really depends if you really, really like those shoes, I guess.
