@Moi: Nope, I suck at math XD Just really good with remembering phone numbers, code, pin numbers and other number sequences
@jacob: I've experienced this color confusion before but for me it's not on a big scale, just some brain haze probably.
But that reminded me of what happened before Christmas. My granny was asking me what to give my bf as a present, and she wondered if maybe a winter jacket would be an idea, but I told her he doesn't like them plus he has a nice coat he likes. A few hours later she comes to me and says she had found some nice male jacket in the closet and that we probably forgot we bought it (yeah, right). So I go to look in the closet and she's showing me this grey jacket and she goes: "see? it's nice, green and male jacket. Did you forget you bought it?" and I was like: "... gramps, it's grey, and it's yours XD" She was so confused xD
