Why is it that so many people, myself included, find it at least somewhat offensive when they find themselves picking up other peoples' expressions and mannerisms? I never said "oh dear" in my life before moving out here, and I find myself speaking the same way that my coworkers do now, not simply using their favorite words. It isn't the end of the world, but it does bother me a bit. On the other hand, I find it weirdly satisfying when I notice someone else picking up my bizarre vocal habits.
Is it simply natural absorption of one's environment, at odds with the instinct to be independent and unique? Is it some kind of jealousy that someone else has discovered a more interesting way of talking? On the other side of things, is it pride that you've made a lasting impact on someone's subconscious mind when you notice them picking up your favorite phrases and habits?
Why don't I mind similarly when I find myself imitating someone on TV?
And why hasn't "that's a load of rich creamery butter" caught on? That phrase is gold.
