The doorbell

Belize fun fact #1: They don't believe in the doorbell. When a person visits a home, it is tradition to stand at the front gate and yell "good day" or "hello" until someone responds from inside. And they don't give up easily, so all of your "let's pretend we aren't home" tricks are completely futile. Trust me, it's always the better option to just answer the door rather than to try and wait out the incessant greetings, which can easily last at least five minutes.
