Помогите сократить текст на пересказ! Заранее спасибо!

Friday is my favourite day of the week because the weekend is starting. Our guests from the Explorers' Club are steying with us this weekend and we want them to enjoy their them here. We have decided to go to Stonehenge on Saturday and to visit the London Zoo on Sunday.
This afternoon, we went to the cinema to see a new American comedy. It was an amazing film and we laughed till we cried.
After the film, we walked a little in Regent's Park. But it started raining and we had to return home.
After dinner, we decided to have a game night and played one of our favorite board games. Olivia and Nikita were happy to join us. Dad is good at Scrabble but Jim prefers Cluedo. He thinks it's fun to find out who the killer is. But this evening we chose Monopoly because Olivia and Nikita could play this game too. So Jim joined us.
We enjoyed the game and played till 11.00 pm. Nikita was the winner. He was lucky to win everybody's money. I wasn't as lucky as Nikita.
After that, we had to look for Tom, my cat. After half an hour, Jim found the naughty cat in the washing machine. Tom was sleeping there. We were very tired and fell asleep at once because we had to get up early in the motning.
