[Alastor, spoken]
I think she likes me

[Alastor's Mother]
Likes you?
Please, Alastor , that's demented
This is why you never should have left
Dear, this whole romance that you've invented
Just proves you're too naive to be here
Why would she like you? Come on now, really?
Look at you, you think that she's impressed?
Don't be a dummy
Come with mummy
Mother-

[Alastor]
No!

[Alastor's Mother, spoken]
No?
Oh, I see how it is

(sung)

Alastor knows best
Alastor's so mature now
Such a clever grown-up mister
Alastor knows best
Fine, if you're so sure now
Go ahead, then give her this

This is why she's here!
Don't let her deceive you!
Give it to her , watch, you'll see!

Trust me, my dear
That's how fast she'll leave you
I won't say I told you so - no
Alastor knows best!
So if she's such a dreamboat
Go and put her to the test

If she's lying
Don't come crying
Mother knows best...
