It's Rubbing Off

I'm starting to think I've been 'in country' too long. The reason for this is I have found myself saying 'yeah-yeah' a lot, and I can't stop. A lot of my Dutch colleagues say it (well 'yah-yah') and I'm assuming I've picked it up from them. I've tried controlling it and I can't, I only realise I've said it after I've spouted it.

Thankfully I haven't taken to saying 'So' at random intervals, which is another popular and strange phrase, but I'm sure it's only a matter of time.
