I strongly disagree with those who say being outgoing, friendly, talkative to strangers or whatever is 'abnormal'. Maybe you wouldn't personally behave that way but it doesn't mean almost everyone else is the same. As an example, I tend to keep to myself but my three sisters will strike up conversations with strangers wherever they go.
If you don't want to RP openly with other people, well, fine. Just don't assume everyone else is like you and claim it's unrealistic or strange to be gregarious.
