Well.. you want to treat her as a friend..but does she treat you
as a friend? You want to be her friend so that you can chase her
right? You want to have every ounce of hope right? Sad to say, all
along she only treated you as a friend and now when she sensed that
you wanted to chase her she is not used to it.
Your only best hope is to leave her alone and dun take it too
personally. The key to girls is not to take them too personally.
Just stay cool and be in control. Dun show that you are affected.
The more you try to press for it, the worse it becomes.
Remember to say hi to her. That's all.
