Great! I'm glad that you did those things. It's terrible to say "misery loves company" but it's really true. Only people who struggle with the same things that you do can totally understand what it's like to live with it on a daily basis.

The thing is Elsa, that other than electrical appliance chargers that glow red/green I don't notice. Being born like that, one has no idea what is "normal" vision, because we never have experienced it..

Exactly! Once I was speaking with someone here or on Facebook who was born without vision. I asked him if he saw black or shadows or what. Never got an answer back.
