As for covering my walls in pictures or the like... I can't really say that I've done many stupid things because of my crush. Though I've stayed away from fan fiction, I did write something. An essay. A 13 page piece on why Henry, in fact, does have a personality and isn't a block of cement (like many have put it). I still have that essay too. I think it took me a whole week to write, and I was really proud of it back then.
I've also used Henry's face as my avatar, PC wallpaper, cellphone wallpaper, you name it. Come to think of it, it's been two years and I still use the same wallpaper on my cell. Seriously. Anyone who flips open my cell can see good ol' Henry holding that bloody axe. And I wouldn't change it for the world.
But I'm extremely embarrassed to admit to people that I secretly harbor an obsession for a character that isn't even real (aren't we all?) I sometimes prefer pixels to people, games to real life... I'm sure we all have our quirks.
But one thing I hate is the fact that crushes get the "aww" effect from others only when you're a kid. I'm currently 20, so my weird obsession automatically makes me that crazy lady who loves fictitious characters... So even though I'll never admit it offline, I'm still proud to hyperventilate in a brown paper bag because of my dear SH4 hero.
