"We'll be peeling some apples when she comes!
When she comes!"

We'll be rolling out some pastry when she comes!
When she comes!

We'll be adding some spices when she comes!
When she comes! 
Hmm. There's no good lyrics for when she goes.
That's just a sad song!
(O.K. Annie just made up the verse below...)
We don't want LaLa Pat to leave.
Oh, we don't want LaLa Pat to leave.
Oh we don't want LaLa Pat,
Oh we don't want LaLa Pat,
Oh we don't want LaLa Pat to leave!
Come back soon.We miss you already!
