"Wow, it sounds like you and I are in the same class. I also have to write 5 metaphors using examples from my life. I don't know where to start."
This project sucks. (That's a metaphor the project does not really suck)
My life has been a sea of troubles.
School life was a breeze.
My father is a rock.
My mother is an angel.
These are very simple examples you could probably do better, but you get the idea.
Always remember:-
Keep your shoulder to the wheel, your nose to the grindstone, and your eye on the ball.
(Now try to work like that)
