I've just been told some exciting news - I'm going on holiday! It's all booked and paid for, but I've not been abroad in so long, I've forgotten the password to get into my safe, which is where my passport is stored - D'Oh!
I do seem to remember that I wrote a mystic kind of clue to help me in this situation... Let me go and look for it - Ah, here it is!
Alas, it hasn't jogged my memory, I've made it too vague.
Here, you look - Can you work it out?
If I was your mate, I'd be your mate's name.
I can make your life easier, you'll be glad I came.
I'm not always a person, but often I am,
I've been on TV and worked on the buses.
I could help with your program.
It's one of my plusses.
If I were given to you, I'd not be returned.
But you may not get me, I have to be earned.
What actually am I? Well it's hard to say,
I guess my action would be known as 'pay'.
Your final clue is merely this
I could be small, or I could be big.
