Oh wow, I remember when me and this person were best friends. We got into a lot fights but from my experience, talking to someone to often causes tension between us so that's probably why.
Geez I haven't had a conversation with this person that was longer than 3 sentences in over a year now. We're just too different now, and we've gone different paths, so that's why we're just acquaintances now, but I kinda miss the times we used to hang out together. :/
