None So Blind
Many Earth sayings are a mystery to me, requiring considerable explanation, or like today, indirect demonstration.
Upon losing my sight, I found my other senses heightened - sharper smells, clearer sounds, battle's adrenaline more bitter on my tongue.
On returning to Earth, this continued, even after the return of my vision.
I noticed subtleties in conversation and glances between Major Carter and DanielJackson, leading me to believe that their feelings for one another are more than friendship; also, that neither knows it yet.
Hence I come to understand the saying "There's none so blind as those who will not see."
