A couple of years ago, my eldest was learning about the Romans in school and he came home one day with the question - how big is the Colosseum dad? Grab your passport and we'll go and find out says I. So off we all went to Rome for a extra long weekend that resulted in us getting back home on the following Tuesday and he went back to school on Wednesday. When his teacher asked the reason why he had missed two days of school, he just looked at her and said that he had to go to Rome to find out how big the Colosseum was because she couldn't teach him that.
