The One
The one person your always happy to see and they are always happy to see you. The one could be hard to find but also could be in plain site. The one is the person who is your best friend, your one love, your soul mate. Without this person you find life meaningless and empty. This person opens your heart and fills it with joy and sweeps away any anger or sorrow. It could take time but you will find this person if they're out there. It could take years or decades but that person is out there.

Guy: i think this girls the one, dude

guy 2: how do you know

guy: i have been searching for years and have never felt like this about any other girl...she is so much better than any of them. I better hold onto her. 😍
