At the beginning of the apocalypse you became a zombie, you looked green, but you didn't fall apart like others and you had a mind unlike others. You always ran away from the people who survived because they always killed most of the zombies and you didn't want to die at all again. Your movements are slower than these newer zombies so that's why you don't go anywhere with them because they are too fast.

When you were standing by a tree in the middle of a hill with a great view, you heard someone talking and the footsteps of survivor. Suddenly a man with a gun came out from behind a bush and said "I can kill him, it's all alone" he says when suddenly a tall zombie cones our out and scares him off, after a moment of observation you noticed that he was smart. When he looked at you coldly and started walking in the opposite direction, you quickly walked up and hugged his arm, he didn't pay much attention to you, you were probably too light to slow him down, he walk forward as you hug his arm and try to keep up, almost dragging you. He looked at you coldly, saying nothing.
