It __________________(MAKE) of natural materials. Besides, the uniform saved a lot of time in the mornings. Now it __________________(TAKE) me hours to decide what to wear. Another thing is that I don’t really like sport. But at school we __________________(PLAY) football, netball, hockey and so on. Sport was compulsory. Now I realise that this was a good thing! And of course there were… holidays! Christmas, Easter, halfterm, and the jackpot — the summer holidays.
