I was chatting with a yank fella I know on Discord and called him mate, I’ve known him for about a year. There was a pause and he said, “That’s the first time you’ve ever called me mate”. Bloke was just about tearing up cos apparently I’d just fulfilled one of his life ambitions, being called mate by an Aussie. Ordinarily I use mate just about every other sentence but it made me realise I must subconsciously tone it down for foreigners.
