Last Riddle (of the year)

Around the corner there is a tree.
Under the tree there is a school.
In the school there is a desk.
Behind the desk there is a bell.
Behind the desk is a teacher.

What is her name?

Riddle is up and waiting

I am a protector.
I sit on a bridge.
One person can see right through me,
while others wonder what I hide.

What am I?

Bonus Riddle

I break, she falls. I break, she falls.

Who am I, and who is she?

It's Tuesday, Time For A Riddle!

A flick of the wrist, and I travel across
Leaving my mark wherever I go
I'm used to make money, but also for fun
I blend and create and cover and show
I'm made of many different materials
Of shapes and sizes, I have a variety
I'm a tool used for communication
But words I don't usually see.

What am I?

EZ Riddle.....or is it?

You will know that I am coming
From the jingle of my bell,
But exactly who I am is not an easy thing to tell.

Children, they adore me
for they find me jolly,
but I do not see them when the halls are decked with holly.

My job often leaves me frozen,
I am a man that all should know,
But I do not do business in times of sleet or ice or snow.

I travel much on business,
But no reindeer haul me around,
I do all my traveling firmly on the ground.

I love the time of Christmas,
But that's not my vocational season,
And I assure that is because of a sound economic reason.

Who am I?
