Football, what does t mean to you

I talked about football in my last post and it made me think about something.

Before I left England for Montreal I made a joke promise to a good friend that I would correct people when they use the term 'soccer'. Now if I say football here in Montreal people assume I am talking about the Canadaian Football so I find myself out of principal saying football but having to explain that I mean soccer.

Sometimes though I have noticed that i slip up and do say soccer. I don't want to lose my Englishisms and am scared that as a few people have mentioned that I am starting to lose my accent.

Have any of you experienced accent loss?
