A youth might be called “Tadeusz” but “Teddy”?! Intolerable! He was “Ted”. His S.I.N. card and passport say, “Ted Victor K....” His medicare card says “Ted K...” while “Thaddeus” decorates his driver's license (he chose "Thaddeus" while at university). The difference on these last two identity cards is mystifying as they are renewed simultaneously.
Sometimes I call him “Charlie”.
