(Breadmaster) It doesn't make any difference, having perfect pitch. It's the change of pitch that is important. The pitch of speech varies so rapidly, even during one syllable, that it is impossible to assign a pitch to it, other than high or low, say. BTW your method of finding north is quite normal and one I use myself, if that's any comfort.
there must be limits, but so far I haven't found one. I even, in my fairly drunken state, remembered the Russian for 'do you mind if I use your toilet', while nipping into a bar in St Petersburg on my merry way back to Ligovskii Prospekt. I may have been born with it, but I don't think I was ever drunk as a child.
[flerdle] It would be interesting for sure. I've been fairly close to the equator but never below it [see? I still see north as 'up' and south as 'down'] Can relate to everything you said earlier about observation, map usage, etc. Even as a child I had a compulsion to know where I was placed and was first to a floor plan, street plan or map - it made my day when faced with one of those pictorial street guide display thingies with a big fat arrow saying YOU ARE HERE!
