Every time a soap skips from one location to another, then another, they always have the same radio station playing and at Christmas, they'll always be listening to carols. I don't know anyone who tunes into a carol-playing radio station at Christmas - is there such a thing?
Space-invading - whenever two people are talking to each other, they stand about 6 inches apart. If someone did this to me in real life, I'd take at least one step back, as they'd be invading my space (unless they were about to snog me!).
Another thing that happens all the time, is two people talking about a third person who is within touching distance and miraculously, can't hear them.
