So frustrating when you have this really cool thing, but you need this other really cool thing to complete it and you can't get your hands on it no matter how hard you try.
I just can't settle for sub-par on this one. It has to be just exactly the thing I'm looking for. I hope I can find it and get my hands on it in time. I shall henceforth make this my mission. Nothing else matters until I can complete this.
Without it, the other half is just incomplete.
