Thx, Kinsao, you are so kind.
And may I continue on letters now ?
I used to love the letter O, because it's the picture of the mouth making the sound ! As I gazed into the letter O, it sent me a visualisation of how it should sound. I was amazed at how a letter could send a vibrating message telling me how to read it.
My other favoured letter used to be K; can't explain too well, but it looked so elegant and balanced with its two limbs branching out of the stem. Kelogg's seemed to have gotten the same telepathic message from the letter.
As for the letter X; it indeed well represents your username. The greek letter sounded like K but often transliterated CH; I don't mind. I was amused to learn my amigo pronounced it like a J, then here I also learned it could be read like an H. What a many-talented letter !
