Answer:
I am very afraid of doing scary activities.
A man who was outside in the rain without an umbrella or hat didn't get a single hair on his head wet. Why?
I have no voice but I can teach you all there is to know. I have spines and hinges but I am not a door. Once I’ve told you all I cannot tell you more.
I am merry creature in pleasant time of year as in but certain seasons I sing that you can hear; And yet I'm made a by-word A very perfect mock; Compared to foolish persons And silliest of all folk.
I have memories, but none of my own. Whatever's on my inside is what is shown. If I'm ever different, it's because you changed me. I feel like a decoration, here for you to arrange me. What am I?
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
