How do I say "to be easily startled" in Japanese?
A friend has told me that he's done a test of courage (肝試し) yesterday at night! He told me it was a scary one and I wanted to respond that
- I would have been scared to death if I had to do a test of courage!
Or
- I couldn't pass a test of courage, because I am scared.
Or
- I am easily startled.
Also is there a word/nickname for someone who is easily startled? Like scaredy-cat, fraidy cat or chicken in English?
