A picnic turned out a disaster

Guys please help me on the topic "a picnic turned out a disaster" I don't know were to start

You need to be more specific. Are you trying to write a story or a poem?

Well.... Start with the beginning ; How you planned this trip and how eagerly you looked forward to it. Dedicate one full para for this. Then talk about the moments how it began to turn negatively. Explain them in detail. Talk about the experience, challenges etc.etc.

I feel this type of writing needs lots of creativity and you just cant follow any stereotype format. I suggest you to do the first draft and post it here so that we could provide you with comments to improve.

Do you have further instruction or that's it?

You should start with a happier picnic. Then you can give a U-turn.
