Where's the jacket?

Where's the jacket
(says Ruby)?

Because it's due to get wet,
because it's supposed to get wet.
A jacket gets dry
but clothes don't.

I'll go out first
'cos I'm smaller than you.
If you have a migraine
we'll have to come back.

Things sometimes go the way we want,
and things sometimes don't.
And if you don't get it,
it's too bad.
