This guy, is really hard to tell what his feelings are. He always looks at me when I'm around, and whenever I look at him, he'll be looking straight at me, then sometimes look away. I wrote a fake love letter and he found out it was from me and when I was reading it, his face was bright red. Then, his sister and him were at church yesterday, and his sister showed him my true feelings for him, and he read it and shook his head and smiled a bit. What does all this mean?
