She found it strange how you can go from telling someone every detail about your day and you even memorize each others daily routines, each others favorite songs. You memorize their scent, you start to slowly use the same vocabulary. You might even recognize their voice between many other people's voices. Sometimes you know a person too well to the point where you can know what they're going to say before they do. From going through all of that to not saying one word. You could've known all of that and memorized every detail about them. But life hits you by surprise and you find out despite everything you thought you knew, you really didn't know the person. You've been fooled. This person you thought you knew the most wasn't the one you had in mind. This wasn't the person you loved, this person wasn't different like everyone else. This wasn't the person who you thought was faithful and loyal. This wasn't the person you figured you'd last with. This wasn't the person that you thought was amazing and showed off to all your friends. This was a person who had lied to you, made a fool out of you, broke you and never even apoligized for it. So, yes she found it strange how you go from seeing a person as your soulmate to a cold hearted stranger.
