Hi,
I just checked
dictionary.com to find out if there is a difference, and
toward and
towards are listed as variants of each other, so interchangeable I suppose. But I thought the quote you pasted was funny because I was thinking
"I doubt I would ever use towards, that sounds crass".
Though I'm from Canada, I
would have guessed it was slangy (North) American English that would use the, in my mind, crasser-sounding "towards". I think I have been away from home so long I don't remember which words I would actually use in regular conversation
I'll check the Collins and the Oxford dictionaries at school tomorrow on usage.
