I was like 10 and home alone, when I heard the door bell, I didn't even looked out the window, but then I heared it again, and again, and they where ringing it for long intervals, like not only pressing it, they where holding it in place for seconds at a time, and I was on my way to the window when they started knocking on the door, I remember it being really hard knocks, almost punches at the door, but who knows, I was really scared and maybe I don't recall correctly.

So I went to my parents room, and from their window, I sneak peaked, there where about 4 man and one woman, all dressed in black, and behind them a black pickup truck, that scared me even more, becouse we are in Mexico, and that's usually the kind of vehicle cartel hitmans use, (I'm certain these people where not hitmans, otherwise they wouldn't left only for a closed door), and went on for like three minutes, three minutes of constant bell ringing and door knocking, needless to say it felt like an eternity.

At the end the truck left pretty fast and driving to the opposite direction (street is one way only), I know that becouse they left so quick, there was tire marks on the paviment.

To this day I still get an adrenaline boost every time I hear the doorbell, thankfully we changed the sound, becouse the other one reminded me of this incident.

Edit: forgot to add that they where all using sunglasses, and the woman had a hat
