You decide you want to switch heights with Jared. You've always been a little self conscious about being on the short side. It would be fun to experience things a few inches higher, it would definitely give you a confidence boost too. There were taller people you could think of, like Eric from your gym, but you thought your neighbor was a good height. Tall but not a complete giant. Jared might not even notice, he hardly stood up from his couch. You close your eyes; your mind is made up. You focus on the man in the next apartment, and think of his height. You draw your lips close, then kiss the ring on your finger.
Rapidly, you feel your posture shift involuntarily. Your back slides up along the frame of the chair a few inches. You stand up, admiring the increased stature. You definitely feel tall. You walk to the bathroom to admire yourself. Your shirt is pulling up a little, making it so that a strip of your belly is exposed. You straighten yourself, and like what you see. It would be nice to be the one looked up to for once. You think about Travis, your boyfriend. He had been your same height, but now you had a solid 4 inches on him. You couldn't wait to show him what had changed.
But then you realize something. When you think about Travis, there are two sets of memories. The thoughts of the two of you going on your first date only a month ago, getting to know each other, kissing for the first time... those seem dim. You can call them to mind, but only by focusing. The memories of Travis you now hold, the ones easily within your grasp, are very different. In these memories, you don't know his name. Just a face passing by in the hall, waiting at your neighbor's door. The voice of a stranger, heard muffled through the walls while Jared moaned in pleasure. No... no. You can't believe it, but your mind tells you otherwise. Travis isn't your boyfriend, he's Jared's. You're single now. You switched relationships with Jared. He got Travis, who made you feel warm and happy, and you were left with nothing. You wonder if Jared has been gay all this time? You didn't know him well enough to be sure. Your extra height, which had been so exciting moments ago, seemed like an overpriced indulgence now.
You kiss the ring, focusing on getting Travis back... and nothing happens. Right, you realize with dread. The ring only works once per day. Looks like you'd have to fix this tomorrow.
