Easy peasy

Since you've been away I can think of nothing to replace you

I never expected to

See that I'm held up looking for problems

What's wrong with you?

Cos if I'm with you it's easy peasy

How do you fancy making a list of things that you might want to do tonight?

Even Sherlock Holmes had a habit

What's wrong with you?

Find me something to hang my coat to, tie a rope to, maybe write a note to, for security

Well if you're with me it's easy peasy

Like all brilliant people I'm a nightmare to be with but I thought you might still want to be with me
