I was born in Swindon but I certainly don't have any west-country in my accent, I think that my voice is generically southern except that I say the short "a" sound in path or glass (as opposed to "parth" or "glarse") if you know what I mean. I can only assume that I inherited it from my mancunian father or my mother who spent some time growing up in Nottingham. At school I was teased that that was a posh way of speaking (and I assumed that that was correct) but now I see that it was just different or northern inflected.
I remember that the second time I met you STN you said something about not being able to remember if I was from north or south from the previous time we met. I can only think that that slight discrepancy is the reason for that. Or else you just have a bad memory. I can't in all honesty think that anyone who spoke to me would think that my origins were anything other than somewhere down south.

Ha, after almost ten years in London I find myself doing that sometimes. In fact I think that in general I'm quite susceptible to talking like people I'm talking to - I'm glad I never spent a lot of time in the US or Australia or somewhere 'cause I think that there is a good chance that I might have picked up the accent.
In my football team there is a one guy who is a geordie who has a strongish accent (to me) but apparently when he first met the other guys in my team (at uni fifteen years ago or so) they literally could not understand what he was saying. When he goes back home he now gets called a southern poof because of how weak his accent is now.
One of the other guys in my team (with a fairly strong cockney accent) went on a driving holiday round Memphis and apparently people were amazed by the way he spoke. People kept begging him to say something in his own language and were generally unable to accept that English was his own language.
