What Happened To This Family On Safari Was Exhilarating...But Terrifying

When you go on a safari, the expectation (or the hope, at least) is that you get up close and personal with the wildlife, while your human environment stays at least slightly removed from the wilderness.
This family got half of what they bargained for...with a bit of a surprise when they forgot to do one crucial thing...

What's this lioness thinking? 

My heart skipped a beat during this video...

There you have it, kids: remember to lock your doors next time you decide to roll through a lion's natural habitat. Wild animals are much smarter - and more curious - than a lot of people realize!
