Likewise, anyone called Donald who call themselves 'Donny'.I’m instinctively wary of people called Ant.
Nobody was called it 15 years ago. At some point quite recently they’ve decided that Anthony or Tony isn’t down with the kids enough and have reinvented themselves.
In other words, they are probably shallow and self-absorbed.
Of course, it could just be Blair’s fault. I too would have distanced myself in anyway possible if I had been a Tony.
