This one would have to be either Shay or Samara.
Shay, because we used to be really close and told each other everything, but these past few months he's gotten really mean and it seems like he doesn't even care anymore, doesn't want to be my friend. It kind of hurts. A lot.
Samara, because we were best friends in primary school, but I guess we've both changed and we're just not as close as we were. I wish we could go back to what we used to have, I miss that.
