Things that make me British

I was so intrigued by the comment about my being “so British” that I thought I’d ask a friend who’s half-American for her thoughts. Was it just my accent (seeing as my addiction to cups of tea was not in evidence at that particular visit) or was there more to it than that? It turns out that it is my mannerisms that make me particularly British – the way I sit and stand (which she described as quite ladylike and ever so slightly prim and proper – I never realised!), my natural politeness, coming across as being slightly reserved and my gestures.
