What's your phobia?

Most of us do fear something...

Even Achilles, a Greek hero of Trojan War, he did fear that his heels would be hit by an arrow...
"Achilles' heel"

Just like a Chinese proverb says, "Once you're bitten by a snake, forever you'll be afraid of rope".
Luckily there was no driving test during his time, or else he will never pass his test...

We may call this one kind of phobia...perhaps in this case, we might say that Achilles' having "arrow-phobia"...

There are so many phobias outside the world...
Some of the commons ones are...

Acrophobia - fear of height

Claustrophobia - fear of confined area

Radiophobia - fear of radio??

However there are some phobias that my common sense just couldn't convince me...
