Hmm .. scary animal encounters, eh?
Scary is .. when you are little, and the animal is big .. or you're big and the animal is VERY dangerous ..
Worst? ..
1. Being 5 years old and bitten badly on the hand by Dad's Red Cloud Kelpie, when I was playing around the full milk cans from the dairy .. the dog was very possessive and considered the cans personal property. The dog got a bullet for his possessiveness.
2. Being 7 years old and being bitten badly on the hand, by brothers horse, on same dairy, when I reached up to pat it .. the horse didn't get a bullet .. it got sold, and I've never liked horses much, since ..
3. Being old enough to know better, and squatting in front of sunbaking freshwater crocodile (the harmless variety, they tell you) .. and upon rising up, quickly, found the crocodile would rise up on its legs and open its jaws ..
Called over 18 year old nephew, and said (classic) .. ''hey, watch this! ..'' and squatted, and raised myself up, two or three times in succession, in front of croc .. each time, having the same result on croc ..
On the fourth try .. croc leaps at me, and takes a good SNAP-P-P!!! .......
Me .. falls backwards in shock ..
Nephew .. rolls on ground, laughing his arse off ..

Not funny ..... find out afterwards .. freshwater crocs will bite humans when annoyed .....
Also .. rising up quickly in front of croc, is a sign of aggression to them .....
