THE BEST KEPT SECRET

Can you keep a secret and promise not to tell ?
Bring your ears closer I don't want to yell
So the secret was given on a cold winter's day 
Should the secret come out there would be hell to pay

I will take this secret to my grave
That is the right and proper way to behave
Always remain silent and promise to keep schtum 
Secrets between best friends more will surely come

I know you are probably wondering what this secret may be
I'm not going to tell as I've been sworn to secrecy
