What a great discussion, Leyla!

As a primary school teacher, #5 is true for me.

So is #1, I love desserts!

Regarding #7, I've never heard that one before, but if someone "is green-fingered" it means that they enjoy and are good at gardening. 

@Micah: Here in Northern Ireland we also use the bun in the oven expression!  I'm pretty sure it's used throughout the UK. 

for me number 5 wich is(He has eyes in the back of his head.)my friends called me with it yesterday when we were playing football and i was the goal keeper when i was talking to my friend out side and sudenlly our competitioner shot the ball and i got it succesfully .it was amazing they said and so they said yhis idiom.   :-)

1. is definitely me.

I learned an idiom in New Zealand which they use to say that a woman is pregnant: "She has a bun in the oven." I always thought that was a funny one.

I 'm just crazy about all of the idioms you wrote but 1 and 2 just show who I used to be when I was a kid. LOL

I've got my hands full but I've got a good head on my shoulders ;)
