If that’s up north it’s probably English sign language and Irish sign language. English and Irish sign language are completely different from each other and come from completely different sign language families. They’re as close as English and Japanese. I think it’s that Ireland uses the European system and England uses the American system but that might not be right. The deaf Taigs up north speak Irish sign language and the deaf Prods use English sign language and the deaf folk from the two communities can’t speak to each other.
