If yesterday you were thinking you spent all morning and afternoon ruining your apartment, maybe your husband will get home from work early. Maybe before you have a chance to say anything, he might happily exclaim, "Wow, everything looks great!" Maybe then your dad might read your blog post and call to find out if he could buy you another can of paint as an early birthday present. Maybe you'll send your dad pictures of the current new paint to get his opinion, and maybe he'll think it looks nice. Maybe it'll start to grow on you, too. Maybe it just wasn't what you were expecting, but maybe it could still be okay.
Hypothetically, the world might start to look a little brighter.
