Just to clarify, she mentions an incident with a tree at the end of the journal and being to scared of jumping to make herself jump. Since I was standing up and the top of my head was under the branch then she was certainly more than 3 feet off the ground (I having been more than 3 feet high for quite a long time now.) =)
What she is doing is taking those long legs of hers into account and granted with them she was somewhere between 3.5 – 4 feet off the ground, her head on the other hand was at least 9.
It was a really neat experience for me. When I was helping her I was being supportive and putting myself out there in ways that I haven’t before and when she didn’t jump I was surprised to find that I wasn’t disappointed; it was enough for me that she had tried as hard as she could. I expected less from myself.
