How long exactly?

It varies dependant on circumstance I think. Something like the Christmas traditions I was quoting could be ascimilated pretty quickly because they are pretty trivial and limited to a small time of year. Going to the same place for half a dozen times can often be described as traditional because it applies to a tiny number of people. Yet when are talking of the traditions of an entire country or culture I think it will take an awful lot longer.

It is the 'how long is peice of string?' question I am afraid. The answer can only ever be 'It depends...'
