Could be that they travel a lot on business but most likely they just think you are an easy target cos you are in a wheelchair. Sorry if I sound too brutal. I get many scammers on Skype if i leave it open for too long, even if I'm just as 'invisible' mostly people who pretend to be in the army, I first say to them : HELLO. follow by WHERE DO I KNOW YOU FROM?
I have a theory that something like in that movie ''Nell'' (1994) with Jodie Foster happened in Ireland.
Perhaps there were some people with some sort of speech impediment that sounded weird and who could only understand each other, they reproduce and took the bizarre language as a natural thing and voilà, the Irish language was born.
