Can you write down eight eights so that they add up to one thousand?

Fate has decided that you will only be pleased to meet me when you need me

Maybe that is why, when I am working, I start working

However annoying I may be to the regulars, the little ones are always inspired

I will always be waiting if you try to reach me

How many of you can guess my name, let me see

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,
I am black blue and grey,
I am read from both ends,
And the same either way.

I am the fastest animal but cannot climb the tree. What am I?

It comprises roots which nobody sees,
Much taller than those trees,
Up and up it goes,
Still it never grows?

When I go in I might cause pain. I cause you to spit and ask you not to swallow. I can fill your hole. What am I?

Before Mount Everest was discovered, what was the highest mountain in the world?

I am soft and cuddly that soothe your heart. But, If you pick my last name I am going to tear you all apart. Who am I?

I’m light as a feather, yet the strongest person can’t hold me for five minutes. What am I?
