You can overhear the television commercial from the next room – and understand what they are talking about.
You know when the aipim (yucca) is not going to be tender and you banter with the vendor to pick out (and show to you) better quality roots.
You feel less inhibited about cutting to the front of the line if you only want to ask a brief question (although this still drives me crazy when others do it!!)
You never, EVER assume the driver in front of you is going to use their turn signal – or if they have it on that it has any connection to their intention to turn or not.

You stop bursting into laughter when you see the price of ordinary things (now you nearly burst into tears).
You know when the knife sharpening guy is nearby, where the pots and pans fix-it guy is, where to get your keys copied, which pharmacy has the best price (usually), which beach is your favorite, how much to pay the parking mafia, and when not to return your friend’s call because they were just being cheap to let it ring and then hang up so you would have to pay.
If you eat GLOBO biscoitinhos in traffic you have moved to native status.
