I used the word 'concur' in an Email to my boss the other day ... it's now being used by all and sundry in various contexts, usually wrongly ... ha ha
I keep sane by constantly repeating to mi'sen "it's only a game, it's only a game"
I used the word 'exacerbate' in an Email today only to receive a response trying to use the word in another context ... it came out as 'exasperate' ... so I had a little chuckle to mi'sen lol
