The school disco is this Friday at 7 pm. Please remember that you don't have to forget to ask your parents for permission. They don't have to speak to your teacher (it's not necessary - just sign the form). You mustn't wear school uniform, but you must wear suitable clothing. Also, you mustn't bring friends from other schools - they aren't allowed in the school. Finally, don't forget - you don't have to dance, but it's much more fun if you do!
