I felt a bit emotional when I listened to the song about kids leaving home in the Mamma Mia movie that Ella was watching.
Me - This song makes me sad because it's about kids leaving home and one day you'll be all grown up and leave me too.
Ella [getting all teary] - Mum! Don't say that! Remember, I will always live with you? And we were going to work together?
Ella - Do you know what makes me sad? When I think about how you are older than me so you are going to die first. [Chokes up again.]
Me - We should stop getting sad about things that won't happen for a long, long time.
Ella - Is that when you will never see me again, when you die?
Me - I suppose so.
Ella - Yes, because if you would come back alive, you'd be a zombie!
That cracked us both up and then we practised our zombie imitation.
