Moms love to worry. It's a hobby. Take mine for example. She won't breathe unless I've safely reached office - a ritual I have to follow every day by giving her a 'missed call' as proof of my arrival at work.

But then you gotta let your mom know that you're fine. And by fine I mean not-crushed-under-a-bus alive. Because no matter where you are or what it is you're doing, it's an unbreakable vow you have to honour. Otherwise, quite literally, she will throw you under that bus herself.

Take this guy for instance. Jonathan Kubben quit his job to travel the world and he's having one helluva time. Whether it's posing with bikini-clad girls or crocodiles, he's definitely doing right by his mom by letting her know that he's fine.

Every photo from his travelogue features 'Mom, I'm fine' placard. Jonathan's Instagram says, "Whatever your age is, if you have a Latin mom and a passion for adventure, you will have to find a way to tell her that you are fine. This is my way."
