1) That's a real pity that this dress costs so much that I can't afford it!

2) Excuse me, sir, but your behaviour is inappropriate, so, I'm afraid, you have to come with me.

3) I refuse to believe you, and I'm sure that it's possible to catch an elephant with this pit!

4) Mummy, I don't want to cut my hair, because I want to be Rapunzel!

5) Please, Dad, switch off your phone - the play is about to begin.

6) Next time we buy 200 balloons for our daughter's birthday, we will ask the seller to blow them up.
