Fuck this fuck everything fuck fuck fuck fuck fuck FUCK
never ever EVER under ANY circumstances, scroll through facebook chat history. It will NEVER end well. You will end up overemotional and afterwards you have to keep reminding yourself that the other person did not scroll through wkth you, so they are in a completely different mondset that you, or than how they were during those facebook chats all that time ago.
Dont do it. Just dont.
