I'll never really understand why

I'll never really understand why I believe you
You're so sly and underhand, I think I'll leave you now
With everything I stole since we met
But I stole no kisses, just some books and the odd cigarette

I never liked anyway,
It must be true what they say

Oh well, you've scuppered my best laid plans,
I can't believe you've just dismiss my pleas right out of hand
I can't believe you've listed everything I stole since we met
But I stole no kisses, just some books and a butterfly net

It's raining,
Now it's sunny,
It's raining,
Now it's sunny
