Everything in your house holds some sort of memory to you. Whether you realize it or not, everything is held in your heart as either a good or a bad memory. It may be the couch in your living room that housed your first kiss, the lamp in your basement that you had in your first house when you were a young child, or that Cure record that you remember listening to in your girlfriend's father's truck. Your brain is able to conjure up an incredible amount of recollections, but most people don't use their minds to their full potential, making it hard to expand your "power center", if you will.
No matter how hard it is for us to block out memories, there is always something around us that will kickstart our brain and bring it back up for us. Like elephants, we never forget. But, somehow, like goldfish, we never remember.
