A memorable weekend
There was a person who thought out a idea that go out for relaxing himself some days ago.But he didn’t know how to relax himself.So he talked this to his friends for seeking advices.Then…
His friends gave him many advices such as hiking around the highway,shopping,mountain climbing or picnic and so on.
“maybe picnic is a interesting experience ” he thought.
And then,he decided to picnic next weekend as well as his friends want to do the same.
per a long time waiting.The weekend had come slowly.On that day morning,he and his another friend left home early to buy the necessary materials for picnic.They went to the supermarket and bought many tasty foods such as chicken,potato,beef and beer and so on.
It was a tough thing for them to take so much time to dispose the materials.It was already 5:00 pm when they completed all the preparation.Then they went to the place where they promised previously.
There were eleven guys total.Both of them were his classmates & friends.Maybe you highly wanted to know what they would do.Yes,you are right,they will hold a barbecue party later.
Firstly,I have to say that the place where they held the picnic party was at the bottom of a mountain.And,there were many ovens be rented from a shop.hence ,they took 120 RMB for renting a even which was very big.
All be ready.It was 6:30pm.The party was beginning.
we baked potato,we drank beers,we were chatting with each other.
It was a interesting experience that we ate the foods which we cooked by ourselves.Didn’t it?
The party went on with happiness and we had to say goodbye when time was 10:00 pm.
It was a memorable weekend for them as well as for me.
p.s.My English is poor,I wrote it out today because I hope someone can indicate the incorrect sentence AND grammar.So,don’t joke me.thanks for your cooperation,thanks for your direction.
