A 100-200 word story about a person / animal / objects whose life would have turned out differently because of something smell-related. Write it from the I-perspective (first person)
The first sentence of the story should contain one of these: I wish/if only I/ I should have / third conditional or mixed conditional.
Apart form this, make sure you make use of all of these at least once:
1) I wish / if only
2) Should have + past participle
3) Third conditional
4) Mixed conditional
Make them bold in your work, so that I can recognise them easily.
