Just write something simple. For instance, your friend's name is Jack (or anything of your choice), and the item of your desire was a bike. You wanted to buy it because you were extremely inspired by a bike race you saw on TV a few weeks/months ago. You managed to get half the money from your dad, but the other half was from a part-time job you worked at as a barista/delivery driver/accountant whatever it is that you applied to solely for the sake of affording the bike.
Now that you've bought the bike, describe your excitement to learn riding it, your happiness of how you reached your goal and so forth. It should be easy.
I'm being vague here in case your assignment is an online one and there is chance of you receiving a plagiarism strike. I hope this helps.
Although Mary isn't fond of reading makes it = complex (dependent clause) she read Harper Lee's To Kill a Mockingbird, and she found it fascinating = compound (2 independent clauses) hope I helped !
