Physical Disability

After claiming "physically disabled" to defer my Mandarin class, all the sudden my knee gets a bit better, or at least I thought so.

I went site visit with the exhibition contractor this morning. I thought I was in a good shape and walked very smoothly. But then the contractor asked what's wrong with my leg.

I think I am too used to my physical disability now that I think everyone walks like me. But the "difference" is still easily noticed by others.
