Harry Potter22. Legilimens
There he sat with a girl that he had just met under a tree, trying to start their first conversation. Harry was so nervous about the things that the girl would tell them. Well, he didn't even know the reason why he should listen to her but then since he was free so it wasn't that bad to know more about others. After all she was his schoolmate.
So he tried to make himself comfy by cooling down those unusual burning cheeks by fanning himself with his hands just like how the girls normally did. He decided that he should take it very seriously and pay a very close attention to what she was going to say. However just as she was about to tell her story, he felt like his head was cracking and it was really hurt. There he was, again. This time he was trying to get through his minds and Harry felt like he has just shot by someone else in his head. He couldn't stand that pain and he fainted.
